-<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 />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Don't stay in bed, unless you can make money in bed. - George Burns",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We didn't lose the game; we just ran out of time. - Vince Lombardi",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"If everything seems under control, you're not going fast enough. - Mario Andretti",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Chance favors the prepared mind - Louis Pasteur"<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo random_element($quotes);</code>
-
-
-<h2>elements()</h2>
-
-<p>Lets you fetch a number of items from an array. The function tests whether each of the array indices is set. If an index does not exist
-it is set to FALSE, or whatever you've specified as the default value via the third parameter. Example:</p>
-
-<code>
-$array = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'radius' => '10',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'diameter' => '20'<br />
-);<br />
-<br />
-$my_shape = elements(array('color', 'shape', 'height'), $array);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => FALSE<br />
-);
-</code>
-
-<p>You can set the third parameter to any default value you like:</p>
-
-<code>
-$my_shape = elements(array('color', 'shape', 'height'), $array, NULL);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => NULL<br />
-);
-</code>
-
-<p>This is useful when sending the <kbd>$_POST</kbd> array to one of your Models. This prevents users from
-sending additional POST data to be entered into your tables:</p>
-
-<code>
-$this->load->model('post_model');<br />
-<br />
-$this->post_model->update(elements(array('id', 'title', 'content'), $_POST));
-</code>
-
-<p>This ensures that only the id, title and content fields are sent to be updated.</p>
