| <h1>Directory Helper</h1> |
| |
| <p>The Directory Helper file contains functions that assist in working with directories.</p> |
| |
| |
| <h2>Loading this Helper</h2> |
| |
| <p>This helper is loaded using the following code:</p> |
| <code>$this->load->helper('directory');</code> |
| |
| <p>The following functions are available:</p> |
| |
| <h2>directory_map('<var>source directory</var>')</h2> |
| |
| <p>This function reads the directory path specified in the first parameter |
| and builds an array representation of it and all its contained files. Example:</p> |
| |
| <code>$map = directory_map('./mydirectory/');</code> |
| |
| <p class="important"><strong>Note:</strong> Paths are almost always relative to your main index.php file.</p> |
| |
| <p>Sub-folders contained within the directory will be mapped as well. If you wish to control the recursion depth, |
| you can do so using the second parameter (integer). A depth of 1 will only map the top level directory:</p> |
| |
| <code>$map = directory_map('./mydirectory/', 1);</code> |
| |
| <p>By default, hidden files will not be included in the returned array. To override this behavior, |
| you may set a third parameter to <var>true</var> (boolean):</p> |
| |
| <code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code> |
| |
| <p>Each folder name will be an array index, while its contained files will be numerically indexed. |
| Here is an example of a typical array:</p> |
| |
| <code>Array<br /> |
| (<br /> |
| [libraries] => Array<br /> |
| (<br /> |
| [0] => benchmark.html<br /> |
| [1] => config.html<br /> |
| [database] => Array<br /> |
| (<br /> |
| [0] => active_record.html<br /> |
| [1] => binds.html<br /> |
| [2] => configuration.html<br /> |
| [3] => connecting.html<br /> |
| [4] => examples.html<br /> |
| [5] => fields.html<br /> |
| [6] => index.html<br /> |
| [7] => queries.html<br /> |
| )<br /> |
| [2] => email.html<br /> |
| [3] => file_uploading.html<br /> |
| [4] => image_lib.html<br /> |
| [5] => input.html<br /> |
| [6] => language.html<br /> |
| [7] => loader.html<br /> |
| [8] => pagination.html<br /> |
| [9] => uri.html<br /> |
| )</code> |
