-<h1>Array Helper</h1>
-
-<p>The Array Helper file contains functions that assist in working with arrays.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('array');</code>
-
-<p>The following functions are available:</p>
-
-<h2>element()</h2>
-
-<p>Lets you fetch an item from an array.  The function tests whether the array index is set and whether it has a value.  If
-a value exists it is returned.  If a value does not exist it returns FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
-
-<code>
-$array = array('color' => 'red', 'shape' => 'round', 'size' => '');<br />
-<br />
-// returns "red"<br />
-echo element('color', $array);<br />
-<br />
-// returns NULL<br />
-echo element('size', $array, NULL);
-</code>
-
-
-<h2>random_element()</h2>
-
-<p>Takes an array as input and returns a random element from it.  Usage example:</p>
-
-<code>$quotes = array(<br />
