-<h1>URL Helper</h1>
-
-<p>The URL Helper file contains functions that assist in working with URLs.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('url');</code>
-
-<p>The following functions are available:</p>
-
-<h2>site_url()</h2>
-
-<p>Returns your site URL, as specified in your config file. The index.php file (or whatever you have set as your
-site <dfn>index_page</dfn> in your config file) will be added to the URL, as will any URI segments you pass to the function.</p>
-
-<p>You are encouraged to use this function any time you need to generate a local URL so that your pages become more portable
-in the event your URL changes.</p>
-
-<p>Segments can be optionally passed to the function as a string or an array. Here is a string example:</p>
-
-<code>echo site_url("news/local/123");</code>
-
-<p>The above example would return something like: http://example.com/index.php/news/local/123</p>
-
-<p>Here is an example of segments passed as an array:</p>
-
-<code>
-$segments = array('news', 'local', '123');<br />
-<br />
-echo site_url($segments);</code>
-
-
-<h2>base_url()</h2>
-<p>Returns your site base URL, as specified in your config file. Example:</p>
-<code>echo base_url();</code>
-
-
-<h2>current_url()</h2>
-<p>Returns the full URL (including segments) of the page being currently viewed.</p>
-
-
-<h2>uri_string()</h2>
-<p>Returns the URI segments of any page that contains this function. For example, if your URL was this:</p>
-<code>http://some-site.com/blog/comments/123</code>
-
-<p>The function would return:</p>
-<code>blog/comments/123</code>
-
-
-<h2>index_page()</h2>
-<p>Returns your site "index" page, as specified in your config file. Example:</p>
-<code>echo index_page();</code>
-
-
-
-<h2>anchor()</h2>
-
-<p>Creates a standard HTML anchor link based on your local site URL:</p>
-
-<code><a href="http://example.com">Click Here</a></code>
-
-<p>The tag has three optional parameters:</p>
-
-<code>anchor(<var>uri segments</var>, <var>text</var>, <var>attributes</var>)</code>
-
-<p>The first parameter can contain any segments you wish appended to the URL. As with the <dfn>site_url()</dfn> function above,
-segments can be a string or an array.</p>
-
-<p><strong>Note:</strong> If you are building links that are internal to your application do not include the base URL (http://...). This
-will be added automatically from the information specified in your config file. Include only the URI segments you wish appended to the URL.</p>
-
-<p>The second segment is the text you would like the link to say. If you leave it blank, the URL will be used.</p>
-
-<p>The third parameter can contain a list of attributes you would like added to the link. The attributes can be a simple string or an associative array.</p>
-
-<p>Here are some examples:</p>
-
-<code>echo anchor('news/local/123', 'My News');</code>
-
-<p>Would produce: <a href="http://example.com/index.php/news/local/123" title="My News">My News</a></p>
-
-<code>echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));</code>
-
-<p>Would produce: <a href="http://example.com/index.php/news/local/123" title="The best news!">My News</a></p>
-
-
-<h2>anchor_popup()</h2>
-
-<p>Nearly identical to the <dfn>anchor()</dfn> function except that it opens the URL in a new window.
-
-You can specify JavaScript window attributes in the third parameter to control how the window is opened. If
-the third parameter is not set it will simply open a new window with your own browser settings. Here is an example
-with attributes:</p>
-
-<code>
-
-$atts = array(<br />
- 'width' => '800',<br />
- 'height' => '600',<br />
- 'scrollbars' => 'yes',<br />
- 'status' => 'yes',<br />
- 'resizable' => 'yes',<br />
- 'screenx' => '0',<br />
- 'screeny' => '0'<br />
- );<br />
-<br />
-echo anchor_popup('news/local/123', 'Click Me!', $atts);</code>
-
-<p>Note: The above attributes are the function defaults so you only need to set the ones that are different from what you need.
-If you want the function to use all of its defaults simply pass an empty array in the third parameter:</p>
-
-<code>echo anchor_popup('news/local/123', 'Click Me!', array());</code>
-
-
-<h2>mailto()</h2>
-
-<p>Creates a standard HTML email link. Usage example:</p>
-
-<code>echo mailto('me@my-site.com', 'Click Here to Contact Me');</code>
-
-<p>As with the <dfn>anchor()</dfn> tab above, you can set attributes using the third parameter.</p>
-
-
-<h2>safe_mailto()</h2>
-
-<p>Identical to the above function except it writes an obfuscated version of the mailto tag using ordinal numbers
-written with JavaScript to help prevent the email address from being harvested by spam bots.</p>
-
-
-<h2>auto_link()</h2>
-
-<p>Automatically turns URLs and email addresses contained in a string into links. Example:</p>
-
-<code>$string = auto_link($string);</code>
-
-<p>The second parameter determines whether URLs and emails are converted or just one or the other. Default behavior is both
-if the parameter is not specified. Email links are encoded as safe_mailto() as shown above.</p>
-
-<p>Converts only URLs:</p>
-<code>$string = auto_link($string, 'url');</code>
-
-<p>Converts only Email addresses:</p>
-<code>$string = auto_link($string, 'email');</code>
-
-<p>The third parameter determines whether links are shown in a new window. The value can be TRUE or FALSE (boolean):</p>
-<code>$string = auto_link($string, 'both', TRUE);</code>
-
-
-<h2>url_title()</h2>
-<p>Takes a string as input and creates a human-friendly URL string. This is useful if, for example, you have a blog
-in which you'd like to use the title of your entries in the URL. Example:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title);<br />
-<br />
-// Produces: whats-wrong-with-css
-</code>
-
-
-<p>The second parameter determines the word delimiter. By default dashes are used. Options are: <dfn>dash</dfn>, or <dfn>underscore</dfn>:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title, 'underscore');<br />
-<br />
-// Produces: whats_wrong_with_css
-</code>
-
-
-<h3>prep_url()</h3>
-<p>This function will add <kbd>http://</kbd> in the event it is missing from a URL. Pass the URL string to the function like this:</p>
-<code>
-$url = "example.com";<br /><br />
-$url = prep_url($url);</code>
-
-
-
-
-<h2>redirect()</h2>
-
-<p>Does a "header redirect" to the local URI specified. Just like other functions in this helper, this one is designed
-to redirect to a local URL within your site. You will <strong>not</strong> specify the full site URL, but rather simply the URI segments
-to the controller you want to direct to. The function will build the URL based on your config file values.</p>
-
-<p>The optional second parameter allows you to choose between the "location"
-method (default) or the "refresh" method. Location is faster, but on Windows servers it can sometimes be a problem. The optional third parameter allows you to send a specific HTTP Response Code - this could be used for example to create 301 redirects for search engine purposes. The default Response Code is 302. The third parameter is <em>only</em> available with 'location' redirects, and not 'refresh'. Examples:</p>
-
-<code>if ($logged_in == FALSE)<br />
-{<br />
- redirect('/login/form/', 'refresh');<br />
-}<br />
-<br />
-// with 301 redirect<br />
-redirect('/article/13', 'location', 301);</code>
-
-<p class="important"><strong>Note:</strong> In order for this function to work it must be used before anything is outputted
-to the browser since it utilizes server headers.<br />
-<strong>Note:</strong> For very fine grained control over headers, you should use the <a href="../libraries/output.html">Output Library</a>'s set_header() function.</p>
