<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 map
only the top level directory set the second parameter to <var>true</var> (boolean):</p>
<code>$map = directory_map('./mydirectory/', TRUE);</code>
<p>By default, hidden files will not be included in the returned array. To override this behavior,
you may set a third parameter to <var>true</var> (boolean):</p>
<code>$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 />
&nbsp;&nbsp;&nbsp;[libraries] => Array<br />
&nbsp;&nbsp;&nbsp;(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => benchmark.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => config.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[database] => Array<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => active_record.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => binds.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => configuration.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[3] => connecting.html<br />

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => email.html<br />

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[6] => language.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[7] => loader.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[8] => pagination.html<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[9] => uri.html<br />
