60 <h1>Directory Helper</h1>
61
62 <p>The Directory Helper file contains functions that assist in working with directories.</p>
63
64
65 <h2>Loading this Helper</h2>
66
67 <p>This helper is loaded using the following code:</p>
68 <code>$this->load->helper('directory');</code>
69
70 <p>The following functions are available:</p>
71
72 <h2>directory_map('<var>source directory</var>')</h2>
73
74 <p>This function reads the directory path specified in the first parameter
75 and builds an array representation of it and all its contained files. Example:</p>
76
77 <code>$map = directory_map('./mydirectory/');</code>
78
79 <p class="important"><strong>Note:</strong> Paths are almost always relative to your main index.php file.</p>
80
81 <p>Sub-folders contained within the directory will be mapped as well.  If you wish to control the recursion depth,
82 you can do so using the second parameter (integer). A depth of 1 will only map the top level directory:</p>
83
84 <code>$map = directory_map('./mydirectory/', 1);</code>
85
86 <p>By default, hidden files will not be included in the returned array.  To override this behavior,
87 you may set a third parameter to <var>true</var> (boolean):</p>
88
89 <code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code>
90
91 <p>Each folder name will be an array index, while its contained files will be numerically indexed.
92 Here is an example of a typical array:</p>
93
94 <code>Array<br />
95 (<br />
96 &nbsp;&nbsp;&nbsp;[libraries] => Array<br />
