<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>
