| 60 | <h1>Compatibility Helper</h1>
|
| 61 |
|
| 62 | <p>The Compatibility Helper file contains PHP 4 implementations of some PHP 5 only native PHP functions and constants. This can be useful
|
| 63 | if you'd like to take advantage of some of these native function but your application may end up running on a PHP 4 server.
|
| 64 | In these cases, it may be advantageous to <a href="../general/autoloader.html">Auto-load</a> the Compatibility Helper so you
|
| 65 | do not have to load it in each controller.</p>
|
| 66 |
|
| 67 | <p class="important"><strong>Note:</strong> There are a few compatibility functions that are in CodeIgniter's native Compat.php file.
|
| 68 | You may use those functions without loading this helper. The functions are split between that file and this Helper so that only
|
| 69 | functions required by the framework are included by default. This way, whether or not you load the additional functions in this Helper
|
| 70 | remains your choice.</p>
|
| 71 |
|
| 72 | <h2>Loading this Helper</h2>
|
| 73 |
|
| 74 | <p>This helper is loaded using the following code:</p>
|
| 75 | <code>$this->load->helper('compatibility');</code>
|
| 76 |
|
| 77 | <h2>Available Constants</h2>
|
| 78 | <p>The following constants are available:</p>
|
| 79 |
|
| 80 | <h3>PHP_EOL</h3>
|
| 81 | <p>The newline character for the server's current OS, e.g. on Windows systems "\r\n", on *nix "\n".
|
| 82 |
|
| 83 | <h2>Available Functions</h2>
|
| 84 | <p>The following functions are available (see linked PHP documentation for documentation):</p>
|
| 85 |
|
| 86 | <h3><a href="http://us.php.net/manual/en/function.file-put-contents.php">file_put_contents()</a> - The fourth parameter, <var>$context</var>, is not supported.</h3>
|
| 87 |
|
| 88 | <h3><a href="http://us.php.net/manual/en/function.fputcsv.php">fputcsv()</a></h3>

|
| 92 | <h3><a href="http://us.php.net/manual/en/function.str-ireplace.php">str_ireplace()</a> - The fourth parameter, <var>$count</var>, is not supported, as PHP 4 would make it become required.</h3>
