-<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 />
- "I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",<br />
- "Don't stay in bed, unless you can make money in bed. - George Burns",<br />
- "We didn't lose the game; we just ran out of time. - Vince Lombardi",<br />
- "If everything seems under control, you're not going fast enough. - Mario Andretti",<br />
- "Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",<br />
- "Chance favors the prepared mind - Louis Pasteur"<br />
- );<br />
-<br />
-echo random_element($quotes);</code>
