<h1>Directory Helper</h1>
62
<p>The Directory Helper file contains functions that assist in working with directories.</p>
65
<h2>Loading this Helper</h2>
67
<p>This helper is loaded using the following code:</p>
68
<code>$this->load->helper('directory');</code>
70
<p>The following functions are available:</p>
72
<h2>directory_map('<var>source directory</var>')</h2>
74
<p>This function reads the directory path specified in the first parameter
75
and builds an array representation of it and all its contained files. Example:</p>
77
<code>$map = directory_map('./mydirectory/');</code>
79
<p class="important"><strong>Note:</strong> Paths are almost always relative to your main index.php file.</p>
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>
84
<code>$map = directory_map('./mydirectory/', 1);</code>
86
<p>By default, hidden files will not be included in the returned array. To override this behavior,
87
you may set a third parameter to <var>true</var> (boolean):</p>
89
<code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code>
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>
96
[libraries] => Array<br />
97
(<br />
98
[0] => benchmark.html<br />
99
[1] => config.html<br />
100
[database] => Array<br />
101
(<br />
102
[0] => active_record.html<br />
103
[1] => binds.html<br />
104
[2] => configuration.html<br />
105
[3] => connecting.html<br />
106
[4] => examples.html<br />
107
[5] => fields.html<br />
108
[6] => index.html<br />
109
[7] => queries.html<br />
110
)<br />
111
[2] => email.html<br />
112
[3] => file_uploading.html<br />
113
[4] => image_lib.html<br />
114
[5] => input.html<br />
115
[6] => language.html<br />
116
[7] => loader.html<br />
117
[8] => pagination.html<br />
118
[9] => uri.html<br />
