<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 />

|

[database] => Array<br />
|
||
|
|

|
||
|
|
[0] => active_record.html<br />
|
||
|
|

|
||
|
|
[2] => email.html<br />
|
||
|
|
[3] => file_uploading.html<br />
|
||
|
|
[4] => image_lib.html<br />
|

[5] => input.html<br />
