-SVN Revision: 1541</p>
-
-<ul>
-	<li>Libraries
-		<ul>
-			<li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>.  It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files.  <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
-			<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
-			<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info.</li>

-			<li>Improved the "auto typography" feature and moved it out of the helper into its own <a href="libraries/typography.html">Typography Class</a>.</li>
-			<li>Improved performance and accuracy of <kbd>xss_clean()</kbd>, including reduction of false positives on image/file tests.</li>
-			<li>Improved <a href="./libraries/parser.html">Parser class</a> to allow multiple calls to the parse() function.  The output of each is appended in the output.</li>
-			<li>Added <dfn>max_filename</dfn> option to set a file name length limit in the  <a href="libraries/file_uploading.html">File Upload Class</a>.</li>
-			<li>Added <dfn>set_status_header()</dfn> function to <a href="libraries/output.html">Output class</a>.</li>
-			<li>Modified <a href="libraries/pagination.html">Pagination</a> class to only output the "First" link when the link for page one would not be shown.</li>
-			<li>Added support for mb_strlen in the <a href="libraries/form_validation.html">Form Validation</a> class so that multi-byte languages will calculate string lengths properly.</li>
-		</ul>
-	</li>
-	<li>Database
-		<ul>
-			<li>Improved Active Record class to allow full path column and table names:  hostname.database.table.column.  Also improved the alias handling.</li>			
-			<li>Improved how table and column names are escaped and prefixed.  It now honors full path names when adding prefixes and escaping.</li>
-			<li>Added Active Record caching feature to "update" and "delete" functions.</li>
-			<li>Added removal of non-printing control characters in <kbd>escape_str()</kbd> of DB drivers that do not have native PHP escaping mechanisms (mssql, oci8, odbc), to avoid potential SQL errors, and possible sources of SQL injection.</li>
-			<li>Added port support to MySQL, MySQLi, and MS SQL database drivers.</li>
-			<li>Added driver name variable in each DB driver, based on bug report #4436.</li>
-		</ul>
-	</li>
-	<li>Helpers
-		<ul>
-			<li>Added several new "setting" functions to the <a href="helpers/form_helper.html">Form helper</a> that allow POST data to be retrieved and set into forms.  These are intended to be used on their own, or with the new <a href="libraries/form_validation.html">Form Validation Class</a>.</li>
-			<li>Added <kbd>current_url()</kbd> and uri_segments() to  <a href="helpers/url_helper.html">URL helper</a>.</li>
-			<li>Altered <kbd>auto_link()</kbd> in the <a href="helpers/url_helper.html">URL helper</a> so that email addresses with "+" included will be linked.</li>
-			<li>Added <kbd>meta()</kbd> function to  <a href="helpers/html_helper.html">HTML helper</a>.</li>
-			<li>Improved accuracy of calculations in <a href="helpers/number_helper.html">Number helper</a>.</li>
-			<li>Removed added newlines ("\n") from most form and html helper functions.</li>
-			<li>Tightened up validation in the <a href="helpers/date_helper.html">Date helper</a> function <kbd>human_to_unix()</kbd>, and eliminated the POSIX regex.</li>

-			<li>Added a file lock check during caching, before trying to write to the file.</li>
-			<li>Modified Cookie key cleaning to unset a few troublesome key names that can be present in certain environments, preventing CI from halting execution.</li>

-<h2>Version 1.4.1</h2>
-<p>Release Date: September 21, 2006</p>

-<li>Added a new feature that passes URI segments directly to your function calls as parameters. See the <a href="controllers.html">Controllers</a> page for more info.</li>
-<li>Added support for a function named <dfn>_output()</dfn>, which when used in your controllers will received the final rendered output from the output class.  More info in the <a href="controllers.html">Controllers</a> page.</li>
-<li>Added several new functions in the <a href="./libraries/uri.html">URI Class</a> to let you retrieve and manipulate URI segments that have been re-routed using the <a href="routing.html">URI Routing</a> feature. Previously, the URI class did not permit you to access any re-routed URI segments, but now it does.</li>

-<li>Fixed an oversight in the upload class. An item mentioned in the 1.4 changelog was missing.</li>
-<li>Added some code to allow email attachments to be reset when sending batches of email.</li>
-<li>Deprecated the <dfn>application/scripts</dfn> folder. It will continue to work for legacy users, but it is recommended that you create your own
-<a href="./general/libraries.html">libraries</a> or <a href="./general/models.html">models</a> instead.  It was originally added before CI had user libraries or models, but it's not needed anymore.</li>
-<li>Deprecated the <dfn>$autoload['core']</dfn> item from the <kbd>autoload.php</kbd> file.  Instead, please now use: <kbd>$autoload['libraries']</kbd></li>

+<h2>Version 1.7</h2>
+<p>Release Date: October 23, 2008<br />
+SVN Revision: 1541</p>
+
+<ul>
+	<li>Libraries
+		<ul>
+			<li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>.  It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files.  <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
+			<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
+			<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info.</li>
+			<li>Added the ability to assign library objects to your own variable names when you use <kbd>$this->load->library()</kbd>. Please see the <a href="libraries/loader.html">Loader class</a> for more info.</li>
+			<li>Added controller class/method info to <a href="general/profiling.html">Profiler class</a> and support for multiple database connections.</li>
+			<li>Improved the "auto typography" feature and moved it out of the helper into its own <a href="libraries/typography.html">Typography Class</a>.</li>
+			<li>Improved performance and accuracy of <kbd>xss_clean()</kbd>, including reduction of false positives on image/file tests.</li>
+			<li>Improved <a href="./libraries/parser.html">Parser class</a> to allow multiple calls to the parse() function.  The output of each is appended in the output.</li>
+			<li>Added <dfn>max_filename</dfn> option to set a file name length limit in the  <a href="libraries/file_uploading.html">File Upload Class</a>.</li>
+			<li>Added <dfn>set_status_header()</dfn> function to <a href="libraries/output.html">Output class</a>.</li>
+			<li>Modified <a href="libraries/pagination.html">Pagination</a> class to only output the "First" link when the link for page one would not be shown.</li>
+			<li>Added support for mb_strlen in the <a href="libraries/form_validation.html">Form Validation</a> class so that multi-byte languages will calculate string lengths properly.</li>
+		</ul>
+	</li>
+	<li>Database
+		<ul>
+			<li>Improved Active Record class to allow full path column and table names:  hostname.database.table.column.  Also improved the alias handling.</li>			
+			<li>Improved how table and column names are escaped and prefixed.  It now honors full path names when adding prefixes and escaping.</li>
+			<li>Added Active Record caching feature to "update" and "delete" functions.</li>
+			<li>Added removal of non-printing control characters in <kbd>escape_str()</kbd> of DB drivers that do not have native PHP escaping mechanisms (mssql, oci8, odbc), to avoid potential SQL errors, and possible sources of SQL injection.</li>
+			<li>Added port support to MySQL, MySQLi, and MS SQL database drivers.</li>
+			<li>Added driver name variable in each DB driver, based on bug report #4436.</li>

+
+<ul>
+<li>Added a <a href="./libraries/unit_testing.html">Unit Testing Library</a>.</li>
+<li>Added the ability to pass objects to the <strong>insert()</strong> and <strong>update()</strong>  database functions.
+This feature enables you to (among other things) use your  <a href="./general/models.html">Model class</a> variables to run queries with. See the Models page for details.</li>
+<li>Added the ability to pass objects to the <a href="./general/views.html">view loading function</a>: $this->load->view('my_view', <var>$object</var>);</li>

+
+
+<h2>Version 1.3</h2>
+<p>Release Date: April 3, 2006</p>
+
+<ul>
+<li>Added support for <a href="models.html">Models</a>.</li>
+<li>Redesigned the database libraries to support additional RDBMs (Postgres, MySQLi, etc.).</li>
+<li>Redesigned the <a href="./database/active_record.html">Active Record class</a> to enable more varied types of queries with simpler syntax, and advanced features like JOINs.</li>
+<li>Added a feature to the database class that lets you run <a href="./database/call_function.html">custom function calls</a>.</li>
+<li>Added support for <a href="controllers.html">private functions</a> in your controllers.  Any controller function name that starts with an underscore will not be served by a URI request.</li>
+<li>Added the ability to pass your own initialization parameters to your <a href="creating_libraries.html">custom core libraries</a> when using $this->load->library()</li>
+<li>Added support for running standard <a href="urls.html">query string URLs</a>.  These can be optionally enabled in your config file.</li>
+<li>Added the ability to  <a href="urls.html">specify a "suffix"</a>, which will be appended to your URLs.  For example, you could add .html to your URLs, making them appear static. This feature is enabled in your config file.</li>
+<li>Added a new error template for use with native PHP errors.</li>
+<li>Added "alternator" function in the <a href="./helpers/string_helper.html">string helpers</a>.</li>

+<li>Change the commenting style in the scripts to the PEAR standard so that IDEs and tools like phpDocumenter can harvest the comments.</li>
+<li>Added better class and function name-spacing to avoid collisions with user developed classes. All CodeIgniter classes are now prefixed with <dfn>CI_</dfn> and
+all controller methods are prefixed with <dfn>_ci</dfn> to avoid controller collisions. A list of reserved function names can be <a href="controllers.html">found here</a>.</li>
+<li>Redesigned how the "CI" super object is referenced, depending on whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful way to manage objects that utilizes a bit less resources.</li>
+<li>Deprecated: <var>$this->db->use_table()</var> has been deprecated. Please read the <a href="./database/active_record.html">Active Record</a> page for information.</li>
+<li>Deprecated: <var>$this->db->smart_escape_str()</var> has been deprecated. Please use this instead: <var>$this->db->escape()</var></li>
+<li>Fixed a bug in the exception handler which was preventing some PHP errors from showing up.</li>
+<li>Fixed a typo in the URI class.  $this->total_segment() should be plural: $this->total_segments()</li>
+<li>Fixed some typos in the default calendar template</li>
+<li>Fixed some typos in the user guide</li>
+</ul>
+
+
+
+
+
+
+
+

+<p>Release Date: March 21, 2006</p>
+
+<ul>
+<li>Redesigned some internal aspects of the framework to resolve scoping problems that surfaced during the beta tests. The problem was most notable when instantiating classes in your constructors, particularly if those classes in turn did work in their constructors.</li>

-		<h2><a name="php_closing_tag"></a>PHP Closing Tag</h2>
-		<div class="guidelineDetails">
-			<p>The PHP closing tag on a PHP document <strong>?&gt;</strong> is optional to the PHP parser.  However, if used, any whitespace following the closing tag, whether introduced 
-				by the developer, user, or an FTP application, can cause unwanted output, PHP errors, or if the latter are suppressed, blank pages.  For this reason, all PHP files should
-				<strong>OMIT</strong> the closing PHP tag, and instead use a comment block to mark the end of file and it's location relative to the application root.
-				This allows you to still identify a file as being complete and not truncated.</p>
-<code><strong>INCORRECT</strong>:
-&lt;?php
-
-echo "Here's my code!";
-
-?&gt;
-
-<strong>CORRECT</strong>:
-&lt;?php
-
-echo "Here's my code!";
-
-/* End of file myfile.php */
-/* Location: ./system/modules/mymodule/myfile.php */
-</code>
-		</div>
-
-	
-		<h2><a name="class_and_method_naming"></a>Class and Method Naming</h2>
-		<div class="guidelineDetails">
-			<p>Class names should always have their first letter uppercase, and the constructor method should match identically.  Multiple words should be separated with an underscore, and not CamelCased.  All other class methods should be entirely lowercased and named to clearly indicate their function, preferably including a verb.  Try to avoid overly long and verbose names.</p>
-
-	<code><strong>INCORRECT</strong>:
-class superclass
-class SuperClass
-
-<strong>CORRECT</strong>:
-class Super_class</code>
-
-			<p>Notice that the Class and constructor methods are identically named and cased:</p>
-
-	<code>class Super_class {
-
-	function Super_class()
-	{
-
-	}
-}</code>
-
-			<p>Examples of improper and proper method naming:</p>
-
-	<code><strong>INCORRECT</strong>:
-function fileproperties()		// not descriptive and needs underscore separator
-function fileProperties()		// not descriptive and uses CamelCase
-function getfileproperties()		// Better!  But still missing underscore separator
-function getFileProperties()		// uses CamelCase
-function get_the_file_properties_from_the_file()	// wordy
-
-<strong>CORRECT</strong>:
-function get_file_properties()	// descriptive, underscore separator, and all lowercase letters</code>
-
-		</div>
-	
-	
-		<h2><a name="variable_names"></a>Variable Names</h2>
-		<div class="guidelineDetails">
-			<p>The guidelines for variable naming is very similar to that used for class methods.  Namely, variables should contain only lowercase letters, use underscore separators, and be reasonably named to indicate their purpose and contents. Very short, non-word variables should only be used as iterators in for() loops.</p>
-<code><strong>INCORRECT</strong>:
-$j = &apos;foo&apos;;		// single letter variables should only be used in for() loops
-$Str			// contains uppercase letters
-$bufferedText		// uses CamelCasing, and could be shortened without losing semantic meaning
-$groupid		// multiple words, needs underscore separator
-$name_of_last_city_used	// too long
-
-<strong>CORRECT</strong>:
-for ($j = 0; $j &lt; 10; $j++)
-$str
-$buffer
-$group_id
-$last_city
-</code>
-		</div>
-	
-	
-		<h2><a name="commenting"></a>Commenting</h2>
-		<div class="guidelineDetails">
-			<p>In general, code should be commented prolifically.  It not only helps describe the flow and intent of the code for less experienced programmers, but can prove invaluable when returning to your own code months down the line.  There is not a required format for comments, but the following are recommended.</p>
-
-			<p><a href="http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.docblock">DocBlock</a> style comments preceding class and method declarations so they can be picked up by IDEs:</p>
-
-<code>/**
- * Super Class
- *
- * @package	Package Name
- * @subpackage	Subpackage
- * @category	Category
- * @author	Author Name
- * @link	http://example.com
- */
-class Super_class {</code>
-
-<code>/**
- * Encodes string for use in XML
- *
- * @access	public
- * @param	string
- * @return	string
- */
-function xml_encode($str)</code>
-
-			<p>Use single line comments within code, leaving a blank line between large comment blocks and code.</p>
-
-<code>// break up the string by newlines
-$parts = explode("\n", $str);
-
-// A longer comment that needs to give greater detail on what is
-// occurring and why can use multiple single-line comments.  Try to
-// keep the width reasonable, around 70 characters is the easiest to
-// read.  Don't hesitate to link to permanent external resources
-// that may provide greater detail:
-//
-// http://example.com/information_about_something/in_particular/
-
-$parts = $this->foo($parts);
-</code>
-		</div>
-	
-	
-		<h2><a name="constants"></a>Constants</h2>
-		<div class="guidelineDetails">
-			<p>Constants follow the same guidelines as do variables, except constants should always be fully uppercase.  <em>Always use ExpressionEngine constants when appropriate, i.e. SLASH, LD, RD, PATH_CACHE, etc.</em></p>
-<code><strong>INCORRECT</strong>:
-myConstant	// missing underscore separator and not fully uppercase
-N		// no single-letter constants
-S_C_VER		// not descriptive
-$str = str_replace('{foo}', 'bar', $str);	// should use LD and RD constants
-
-<strong>CORRECT</strong>:
-MY_CONSTANT
-NEWLINE
-SUPER_CLASS_VERSION
-$str = str_replace(LD.'foo'.RD, 'bar', $str);
-</code>
-		</div>
-	
-	
-		<h2><a name="true_false_and_null"></a>TRUE, FALSE, and NULL</h2>
-		<div class="guidelineDetails">
-			<p><strong>TRUE</strong>, <strong>FALSE</strong>, and <strong>NULL</strong> keywords should always be fully uppercase.</p>
-<code><strong>INCORRECT</strong>:
-if ($foo == true)
-$bar = false;
-function foo($bar = null)
-
-<strong>CORRECT</strong>:
-if ($foo == TRUE)
-$bar = FALSE;
-function foo($bar = NULL)</code>
-		</div>
-	
-
-	
-		<h2><a name="logical_operators"></a>Logical Operators</h2>
-		<div class="guidelineDetails">
-			<p>Use of <strong>||</strong> is discouraged as its clarity on some output devices is low (looking like the number 11 for instance).
-				<strong>&amp;&amp;</strong> is preferred over <strong>AND</strong> but either are acceptable, and a space should always precede and follow <strong>!</strong>.</p>
-<code><strong>INCORRECT</strong>:
-if ($foo || $bar)
-if ($foo AND $bar)  // okay but not recommended for common syntax highlighting applications
-if (!$foo)
-if (! is_array($foo))

-		<div class="guidelineDetails">
-			<p>Some PHP functions return FALSE on failure, but may also have a valid return value of "" or 0, which would evaluate to FALSE in loose comparisons.  Be explicit by comparing the variable type when using these return values in conditionals to ensure the return value is indeed what you expect, and not a value that has an equivalent loose-type evaluation.</p>
-			<p>Use the same stringency in returning and checking your own variables.  Use <strong>===</strong> and <strong>!==</strong> as necessary.
-
-<code><strong>INCORRECT</strong>:
-// If 'foo' is at the beginning of the string, strpos will return a 0,
-// resulting in this conditional evaluating as TRUE
-if (strpos($str, 'foo') == FALSE)
-
-<strong>CORRECT</strong>:
-if (strpos($str, 'foo') === FALSE)
-</code>
-
-<code><strong>INCORRECT</strong>:
-function build_string($str = "")
-{
-	if ($str == "")	// uh-oh!  What if FALSE or the integer 0 is passed as an argument?
-	{
-
-	}
-}
-
-<strong>CORRECT</strong>:
-function build_string($str = "")
-{
-	if ($str === "")

-}</code>
-
-		<p>See also information regarding <a href="http://us3.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting">typecasting</a>, which can be quite useful.  Typecasting has a slightly different effect which may be desirable.  When casting a variable as a string, for instance, NULL and boolean FALSE variables become empty strings, 0 (and other numbers) become strings of digits, and boolean TRUE becomes "1":</p>

-		<h2><a name="whitespace_in_files"></a>Whitespace in Files</h2>
-		<div class="guidelineDetails">
-			<p>No whitespace can precede the opening PHP tag or follow the closing PHP tag.  ExpressionEngine output is buffered, so whitespace in your files can cause output to begin before ExpressionEngine outputs its content, leading to errors and an inability for ExpressionEngine to send proper headers.  In the examples below, select the text with your mouse to reveal the incorrect whitespace.</p>
-
-			<p><strong>INCORRECT</strong>:</p>
-<code>     
-&lt;?php

-		<h2><a name="compatibility"></a>Compatibility</h2>
-		<div class="guidelineDetails">
-			<p>Unless specifically mentioned in your add-on's documentation, all code must be compatible with PHP version 4.3+.  Additionally, do not use PHP functions that require non-default libraries to be installed unless your code contains an alternative method when the function is not available, or you implicitly document that your add-on requires said PHP libraries.</p>

-		<h2><a name="class_and_file_names_using_common_words"></a>Class and File Names using Common Words</h2>
-		<div class="guidelineDetails">
-			<p>When your class or filename is a common word, or might quite likely be identically named in another PHP script, provide a unique prefix to help prevent collision.  Always realize that your end users may be running other add-ons or third party PHP scripts.  Choose a prefix that is unique to your identity as a developer or company.</p>
-
-<code><strong>INCORRECT</strong>:
-class Email		pi.email.php

-		<h2><a name="database_table_names"></a>Database Table Names</h2>
-		<div class="guidelineDetails">
-			<p>Any tables that your add-on might use must use the 'exp_' prefix, followed by a prefix uniquely identifying you as the developer or company, and then a short descriptive table name.  You do not need to be concerned about the database prefix being used on the user's installation, as ExpressionEngine's database class will automatically convert 'exp_' to what is actually being used.</p>
-
-<code><strong>INCORRECT</strong>:
-email_addresses		// missing both prefixes
-pre_email_addresses	// missing exp_ prefix
-exp_email_addresses	// missing unique prefix

-<strong>CORRECT</strong>:
-exp_pre_email_addresses
-</code>
-
-			<p class="important"><strong>NOTE:</strong> Be mindful that MySQL has a limit of 64 characters for table names.  This should not be an issue as table names that would exceed this would likely have unreasonable names.  For instance, the following table name exceeds this limitation by one character.  Silly, no? <strong>exp_pre_email_addresses_of_registered_users_in_seattle_washington</strong>

-		<h2><a name="one_file_per_class"></a>One File per Class</h2>
-		<div class="guidelineDetails">
-			<p>Use separate files for each class your add-on uses, unless the classes are <em>closely related</em>.  An example of ExpressionEngine files that contains multiple classes is the Database class file, which contains both the DB class and the DB_Cache class, and the Magpie plugin, which contains both the Magpie and Snoopy classes.</p>

-
-	
-		<h2><a name="whitespace"></a>Whitespace</h2>
-		<div class="guidelineDetails">
-			<p>Use tabs for whitespace in your code, not spaces.  This may seem like a small thing, but using tabs instead of whitespace allows the developer looking at your code to have indentation at levels that they prefer and customize in whatever application they use.  And as a side benefit, it results in (slightly) more compact files, storing one tab character versus, say, four space characters.</p>

-			<p>Make sure that while developing your add-on, error reporting is enabled for ALL users, and that display_errors is enabled in the PHP environment.  You can check this setting with:</p>
-
-<code>if (ini_get('display_errors') == 1)

-
-			<p>On some servers where display_errors is disabled, and you do not have the ability to change this in the php.ini, you can often enable it with:</p>

-
-			<p class="important"><strong>NOTE:</strong> Setting the <a href="http://us.php.net/manual/en/ref.errorfunc.php#ini.display-errors">display_errors</a> setting with ini_set() at runtime is not identical to having it enabled in the PHP environment.

+		<h2><a name="class_and_method_naming"></a>Class and Method Naming</h2>
+		<div class="guidelineDetails">
+			<p>Class names should always have their first letter uppercase, and the constructor method should match identically.  Multiple words should be separated with an underscore, and not CamelCased.  All other class methods should be entirely lowercased and named to clearly indicate their function, preferably including a verb.  Try to avoid overly long and verbose names.</p>

+			<p>The guidelines for variable naming is very similar to that used for class methods.  Namely, variables should contain only lowercase letters, use underscore separators, and be reasonably named to indicate their purpose and contents. Very short, non-word variables should only be used as iterators in for() loops.</p>
+<code><strong>INCORRECT</strong>:

+		<h2><a name="comparing_return_values_and_typecasting"></a>Comparing Return Values and Typecasting</h2>
+		<div class="guidelineDetails">
+			<p>Some PHP functions return FALSE on failure, but may also have a valid return value of "" or 0, which would evaluate to FALSE in loose comparisons.  Be explicit by comparing the variable type when using these return values in conditionals to ensure the return value is indeed what you expect, and not a value that has an equivalent loose-type evaluation.</p>
+			<p>Use the same stringency in returning and checking your own variables.  Use <strong>===</strong> and <strong>!==</strong> as necessary.
+
+<code><strong>INCORRECT</strong>:
+// If 'foo' is at the beginning of the string, strpos will return a 0,
+// resulting in this conditional evaluating as TRUE
+if (strpos($str, 'foo') == FALSE)
+
+<strong>CORRECT</strong>:
+if (strpos($str, 'foo') === FALSE)
+</code>
+
+<code><strong>INCORRECT</strong>:
+function build_string($str = "")
+{
+	if ($str == "")	// uh-oh!  What if FALSE or the integer 0 is passed as an argument?
+	{
+
+	}
+}
+
+<strong>CORRECT</strong>:
+function build_string($str = "")
+{
+	if ($str === "")
+	{
+
+	}
+}</code>
+
+		<p>See also information regarding <a href="http://us3.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting">typecasting</a>, which can be quite useful.  Typecasting has a slightly different effect which may be desirable.  When casting a variable as a string, for instance, NULL and boolean FALSE variables become empty strings, 0 (and other numbers) become strings of digits, and boolean TRUE becomes "1":</p>
+
+<code>$str = (string) $str;	// cast $str as a string</code>

+		<h2><a name="debugging_code"></a>Debugging Code</h2>
+		<div class="guidelineDetails">
+			<p>No debugging code can be left in place for submitted add-ons unless it is commented out, i.e. no var_dump(), print_r(), die(), and exit() calls that were used while creating the add-on, unless they are commented out.</p>
+
+<code>// print_r($foo);</code>
+		</div>
+	
+
+	
+		<h2><a name="whitespace_in_files"></a>Whitespace in Files</h2>
+		<div class="guidelineDetails">
+			<p>No whitespace can precede the opening PHP tag or follow the closing PHP tag.  ExpressionEngine output is buffered, so whitespace in your files can cause output to begin before ExpressionEngine outputs its content, leading to errors and an inability for ExpressionEngine to send proper headers.  In the examples below, select the text with your mouse to reveal the incorrect whitespace.</p>
+
+			<p><strong>INCORRECT</strong>:</p>
+<code>     
+&lt;?php
+	// ...there is whitespace and a linebreak above the opening PHP tag
+	// as well as whitespace after the closing PHP tag
+?&gt;    
+</code>
+			<p><strong>CORRECT</strong>:</p>
+<code>&lt;?php
+	// this sample has no whitespace before or after the opening and closing PHP tags
+?&gt;</code>
+
+		</div>
+	
+	
+		<h2><a name="compatibility"></a>Compatibility</h2>
+		<div class="guidelineDetails">
+			<p>Unless specifically mentioned in your add-on's documentation, all code must be compatible with PHP version 4.3+.  Additionally, do not use PHP functions that require non-default libraries to be installed unless your code contains an alternative method when the function is not available, or you implicitly document that your add-on requires said PHP libraries.</p>
+		</div>
+		
+
+	
+		<h2><a name="class_and_file_names_using_common_words"></a>Class and File Names using Common Words</h2>
+		<div class="guidelineDetails">
+			<p>When your class or filename is a common word, or might quite likely be identically named in another PHP script, provide a unique prefix to help prevent collision.  Always realize that your end users may be running other add-ons or third party PHP scripts.  Choose a prefix that is unique to your identity as a developer or company.</p>
+
+<code><strong>INCORRECT</strong>:
+class Email		pi.email.php
+class Xml		ext.xml.php
+class Import		mod.import.php
+
+<strong>CORRECT</strong>:
+class Pre_email		pi.pre_email.php
+class Pre_xml		ext.pre_xml.php
+class Pre_import	mod.pre_import.php
+</code>
+		</div>
+	
+	
+		<h2><a name="database_table_names"></a>Database Table Names</h2>
+		<div class="guidelineDetails">
+			<p>Any tables that your add-on might use must use the 'exp_' prefix, followed by a prefix uniquely identifying you as the developer or company, and then a short descriptive table name.  You do not need to be concerned about the database prefix being used on the user's installation, as ExpressionEngine's database class will automatically convert 'exp_' to what is actually being used.</p>
+
+<code><strong>INCORRECT</strong>:
+email_addresses		// missing both prefixes
+pre_email_addresses	// missing exp_ prefix
+exp_email_addresses	// missing unique prefix
+
+<strong>CORRECT</strong>:
+exp_pre_email_addresses
+</code>
+
+			<p class="important"><strong>NOTE:</strong> Be mindful that MySQL has a limit of 64 characters for table names.  This should not be an issue as table names that would exceed this would likely have unreasonable names.  For instance, the following table name exceeds this limitation by one character.  Silly, no? <strong>exp_pre_email_addresses_of_registered_users_in_seattle_washington</strong>
+		</div>
+	
+
+	
+		<h2><a name="one_file_per_class"></a>One File per Class</h2>
+		<div class="guidelineDetails">
+			<p>Use separate files for each class your add-on uses, unless the classes are <em>closely related</em>.  An example of ExpressionEngine files that contains multiple classes is the Database class file, which contains both the DB class and the DB_Cache class, and the Magpie plugin, which contains both the Magpie and Snoopy classes.</p>
+		</div>
+	
+
+	
+		<h2><a name="whitespace"></a>Whitespace</h2>
+		<div class="guidelineDetails">
+			<p>Use tabs for whitespace in your code, not spaces.  This may seem like a small thing, but using tabs instead of whitespace allows the developer looking at your code to have indentation at levels that they prefer and customize in whatever application they use.  And as a side benefit, it results in (slightly) more compact files, storing one tab character versus, say, four space characters.</p>
+		</div>
+	
+
+	
+		<h2><a name="line_breaks"></a>Line Breaks</h2>
+		<div class="guidelineDetails">
+			<p>Files must be saved with Unix line breaks.  This is more of an issue for developers who work in Windows, but in any case ensure that your text editor is setup to save files with Unix line breaks.</p>
+		</div>
+	
+
+	
+		<h2><a name="code_indenting"></a>Code Indenting</h2>
+		<div class="guidelineDetails">
+			<p>Use Allman style indenting.  With the exception of Class declarations, braces are always placed on a line by themselves, and indented at the same level as the control statement that "owns" them.</p>
+
+<code><strong>INCORRECT</strong>:
+function foo($bar) {
+	// ...
+}
+
+foreach ($arr as $key => $val) {
+	// ...

+		</div>
+	
+
+	<h2><a name="bracket_spacing"></a>Bracket and Parenthetic Spacing</h2>
+		<div class="guidelineDetails">
+			<p>In general, parenthesis and brackets should not use any additional spaces.  The exception is that a space should always follow PHP control structures that accept arguments with parenthesis (declare, do-while, elseif, for, foreach, if, switch, while), to help distinguish them from functions and increase readability.</p>
+			
+<code>INCORRECT:
+$arr[ $foo ] = 'foo';

+$arr[$foo] = 'foo'; // no spaces around array keys
+
+
+INCORRECT:

+
+
+INCORRECT:

+
+CORRECT:

+	
+		<h2><a name="localized_text_in_control_panel"></a>Localized Text in Control Panel</h2>
+		<div class="guidelineDetails">
+			<p>Any text that is output in the control panel should use language variables in your module's lang file to allow localization.</p>
+
+<code>INCORRECT:
+return "Invalid Selection";
+
+CORRECT:
+return $LANG->line('invalid_selection');</code>
+		</div>
+	
+
+	
+		<h2><a name="private_methods_and_variables"></a>Private Methods and Variables</h2>
+		<div class="guidelineDetails">
+			<p>Methods and variables that are only accessed internally by your class, such as utility and helper functions that your public methods use for code abstraction, should be prefixed with an underscore.</p>
+
+<code>convert_text()		// public method
+_convert_text()		// private method</code>
+		</div>
+	
+
+	
+		<h2><a name="php_errors"></a>PHP Errors</h2>
+		<div class="guidelineDetails">
+			<p>Code must run error free and not rely on warnings and notices to be hidden to meet this requirement.  For instance, never access a variable that you did not set yourself (such as $_POST array keys) without first checking to see that it isset().</p>
+
+			<p>Make sure that while developing your add-on, error reporting is enabled for ALL users, and that display_errors is enabled in the PHP environment.  You can check this setting with:</p>
+
+<code>if (ini_get('display_errors') == 1)
+{
+	exit "Enabled";
+}</code>
+
+			<p>On some servers where display_errors is disabled, and you do not have the ability to change this in the php.ini, you can often enable it with:</p>
+
+<code>ini_set('display_errors', 1);</code>
+
+			<p class="important"><strong>NOTE:</strong> Setting the <a href="http://us.php.net/manual/en/ref.errorfunc.php#ini.display-errors">display_errors</a> setting with ini_set() at runtime is not identical to having it enabled in the PHP environment.  Namely, it will not have any effect if the script has fatal errors</p>
+		</div>
+	
+
+	
+		<h2><a name="short_open_tags"></a>Short Open Tags</h2>
+		<div class="guidelineDetails">
+			<p>Always use full PHP opening tags, in case a server does not have short_open_tag enabled.</p>
+
+<code><strong>INCORRECT</strong>:
+&lt;? echo $foo; ?&gt;
+
+&lt;?=$foo?&gt;
+

+</code>
+		</div>
+	
+
+	
+		<h2><a name="strings"></a>Strings</h2>
+		<div class="guidelineDetails">
+			<p>Always use single quoted strings unless you need variables parsed, and in cases where you do need variables parsed, use braces to prevent greedy token parsing.  You may also use double-quoted strings if the string contains single quotes, so you do not have to use escape characters.</p>
+
+<code><strong>INCORRECT</strong>:
+"My String"					// no variable parsing, so no use for double quotes
+"My string $foo"				// needs braces
+'SELECT foo FROM bar WHERE baz = \'bag\''	// ugly
+
+<strong>CORRECT</strong>:
+'My String'
+"My string {$foo}"
+"SELECT foo FROM bar WHERE baz = 'bag'"</code>
+		</div>
+	
+
+	
+		<h2><a name="sql_queries"></a>SQL Queries</h2>
+		<div class="guidelineDetails">
+			<p>MySQL keywords are always capitalized: SELECT, INSERT, UPDATE, WHERE, AS, JOIN, ON, IN, etc.</p>
+
+			<p>Break up long queries into multiple lines for legibility, preferably breaking for each clause.</p>
+
+<code><strong>INCORRECT</strong>:
+// keywords are lowercase and query is too long for
+// a single line (... indicates continuation of line)
+$query = $this->db->query("select foo, bar, baz, foofoo, foobar as raboof, foobaz from exp_pre_email_addresses
+...where foo != 'oof' and baz != 'zab' order by foobaz limit 5, 100");
+
+<strong>CORRECT</strong>:

+		</div>
+	
+
+	
+		<h2><a name="default_function_arguments"></a>Default Function Arguments</h2>
+		<div class="guidelineDetails">
+			<p>Whenever appropriate, provide function argument defaults, which helps prevent PHP errors with mistaken calls and provides common fallback values which can save a few lines of code. Example:</p>
+
+<code>function foo($bar = '', $baz = FALSE)</code>
+		</div>
+	
+
+	
+		<h2><a name="overlapping_tag_parameters"></a>Overlapping Tag Parameters</h2>
+		<div class="guidelineDetails">
+			<p>Avoid multiple tag parameters that have effect on the same thing.  For instance, instead of <strong>include=</strong> and <strong>exclude=</strong>, perhaps allow <strong>include=</strong> to handle the parameter alone, with the addition of "not", e.g. <strong>include="not bar"</strong>.  This will prevent problems of parameters overlapping or having to worry about which parameter has priority over another.</p>

-<h1>HTML Helper</h1>
-
-<p>The HTML Helper file contains functions that assist in working with HTML.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('html');</code>
-
-<p>The following functions are available:</p>
-
-<h2>br()</h2>
-<p>Generates line break tags (&lt;br />) based on the number you submit. Example:</p>
-<code>echo br(3);</code>
-<p>The above would produce: &lt;br />&lt;br />&lt;br /></p>
-
-<h2>heading()</h2>
-<p>Lets you create HTML &lt;h1> tags.  The first parameter will contain the data, the
-second the size of the heading.  Example:</p>
-<code>echo heading('Welcome!', 3);</code>
-<p>The above would produce:  &lt;h3>Welcome!&lt;/h3></p>
-<h2>img()</h2>
-<p>Lets you create HTML &lt;img /&gt; tags.  The first parameter  contains the image source. Example:</p>
-<code>echo img('images/picture.jpg');<br />
-// gives &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
-<p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p>
-<p><code>echo img('images/picture.jpg', TRUE);<br />
-// gives &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; /&gt;</code></p>
-<p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values.</p>
-<p><code> $image_properties = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'post_images',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />
-	);<br />
-	<br />
-	img($image_properties);<br />
-	// &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;Me, demonstrating how to eat 4 slices of pizza at one time&quot; class=&quot;post_images&quot; width=&quot;200&quot; height=&quot;200&quot; title=&quot;That was quite a night&quot; rel=&quot;lightbox&quot; /&gt;</code></p>
-<h2>link_tag()</h2>
-<p>Lets you create HTML &lt;link /> tags.  This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code>
-echo link_tag('css/mystyles.css');<br />
-// gives &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
-<p>Further examples:</p>
-
-<code>
-	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
-	// &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt; 
-	<br />
-	<br />
-	echo link('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
-	// &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
-<p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p>
-<p><code>
-	$link = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
-	);<br />
-	<br />
-	echo link_tag($link);<br />
-	// &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>
-	
-<h2>nbs()</h2>
-<p>Generates non-breaking spaces (&amp;nbsp;) based on the number you submit. Example:</p>
-<code>echo nbs(3);</code>
-<p>The above would produce: &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>
-
-<h2>ol()&nbsp; and&nbsp; ul()</h2>
-
-<p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />
-$list = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo ul($list, $attributes);<br />
-</code>
-
-<p>The above code will produce this:</p>
-
-<code>
-&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
-&nbsp;&nbsp;&lt;li>red&lt;/li><br />
-&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
-&nbsp;&nbsp;&lt;li>green&lt;/li><br />
-&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
-&lt;/ul>
-</code>
-
-<p>Here is a more complex example, using a multi-dimensional array:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />

-&nbsp;&nbsp;&lt;/li&gt;<br />
-&lt;/ul&gt;
-</code>
-
-
-
-<h2>meta()</h2>
-
-<p>Helps you generate meta tags.  You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p>
-
-<code>
-echo meta('description', 'My Great site');<br />
-// Generates:  &lt;meta name="description" content="My Great Site" /><br />
-<br /><br />
-
-echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter.  Can be "equiv" or "name"<br />
-// Generates:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />
-
-<br /><br />
-
-echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
-// Generates:  &lt;meta name="robots" content="no-cache" /><br />
-
-<br /><br />
-
-$meta = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'description', 'content' => 'My Great Site'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo meta($meta);
-<br />
-// Generates:  <br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta name="description" content="My Great Site" /><br />
-// &lt;meta name="keywords" content="love, passion, intrigue, deception" /><br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" />
-</code>
-
-
-<h2>doctype()</h2>
-
-<p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p>
-
-<code>
-echo docytype();<br />
-// &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;<br />
-<br />
-echo doctype('html4-trans');<br />
-// &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
-</code>
-
-<p>The following is a list of doctype choices.  These are configurable, and pulled from <samp>application/config/doctypes.php</samp></p>

+<h1>HTML Helper</h1>
+
+<p>The HTML Helper file contains functions that assist in working with HTML.</p>
+
+
+<h2>Loading this Helper</h2>
+
+<p>This helper is loaded using the following code:</p>
+<code>$this->load->helper('html');</code>
+
+<p>The following functions are available:</p>
+
+<h2>br()</h2>
+<p>Generates line break tags (&lt;br />) based on the number you submit. Example:</p>
+<code>echo br(3);</code>
+<p>The above would produce: &lt;br />&lt;br />&lt;br /></p>
+
+<h2>heading()</h2>
+<p>Lets you create HTML &lt;h1> tags.  The first parameter will contain the data, the
+second the size of the heading.  Example:</p>
+<code>echo heading('Welcome!', 3);</code>
+<p>The above would produce:  &lt;h3>Welcome!&lt;/h3></p>
+<h2>img()</h2>
+<p>Lets you create HTML &lt;img /&gt; tags.  The first parameter  contains the image source. Example:</p>
+<code>echo img('images/picture.jpg');<br />
+// gives &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
+<p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p>
+<p><code>echo img('images/picture.jpg', TRUE);<br />
+// gives &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; /&gt;</code></p>
+<p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values.</p>
+<p><code> $image_properties = array(<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />

+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />

+<h2>link_tag()</h2>
+<p>Lets you create HTML &lt;link /> tags.  This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code>
+echo link_tag('css/mystyles.css');<br />
+// gives &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
+<p>Further examples:</p>
+
+<code>
+	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
+	// &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt; 
+	<br />
+	<br />
+	echo link('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
+	// &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
+<p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p>
+<p><code>
+	$link = array(<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
+	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
+	);<br />
+	<br />
+	echo link_tag($link);<br />
+	// &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>
+	
+<h2>nbs()</h2>
+<p>Generates non-breaking spaces (&amp;nbsp;) based on the number you submit. Example:</p>
+<code>echo nbs(3);</code>
+<p>The above would produce: &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>
+
+<h2>ol()&nbsp; and&nbsp; ul()</h2>
+
+<p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p>
+
+<code>
+$this->load->helper('html');<br />
+<br />
+$list = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+<br />
+$attributes = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+<br />
+echo ul($list, $attributes);<br />
+</code>
+
+<p>The above code will produce this:</p>
+
+<code>
+&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
+&nbsp;&nbsp;&lt;li>red&lt;/li><br />
+&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
+&nbsp;&nbsp;&lt;li>green&lt;/li><br />
+&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
+&lt;/ul>
+</code>
+
+<p>Here is a more complex example, using a multi-dimensional array:</p>
+
+<code>
+$this->load->helper('html');<br />
+<br />
+$list = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'colors' => array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'shapes' => array(<br />

+
+
+
+<h2>meta()</h2>
+
+<p>Helps you generate meta tags.  You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p>
+
+<code>
+echo meta('description', 'My Great site');<br />
+// Generates:  &lt;meta name="description" content="My Great Site" /><br />
+<br /><br />
+
+echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter.  Can be "equiv" or "name"<br />
+// Generates:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />
+
+<br /><br />
+
+echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
+// Generates:  &lt;meta name="robots" content="no-cache" /><br />
+
+<br /><br />
+
+$meta = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'description', 'content' => 'My Great Site'),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br />

+// &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" />
+</code>
+
+
+<h2>doctype()</h2>
+
+<p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p>
+
+<code>
+echo docytype();<br />
+// &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;<br />

+// &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
+</code>
+
+<p>The following is a list of doctype choices.  These are configurable, and pulled from <samp>application/config/doctypes.php</samp></p>
+
