How to Sort Multidimensional Arrays Using PHP

gistfile1.php

<?php
$arr = 	array(
		array('name' => 'John', 'age' => 30, 'website' => 'http://learnphp.co'),
		array('name' => 'Joe', 'age' => 28, 'website' => 'http://johnmorrisonline.com'),
		array('name' => 'Amy', 'age' => 32, 'website' => 'http://amy.com'),
		array('name' => 'Alex', 'age' => 22, 'website' => 'http://thealex.com'),
		array('name' => 'Pat', 'age' => 40, 'website' => 'http://patsjourney.com'),
);
	
?>

<pre><?php print_r($arr); ?></pre>

<?php
	array_multisort($arr);
?>

<pre><?php print_r($arr); ?></pre>

<?php
	function val_sort($array,$key) {
	
	//Loop through and get the values of our specified key
	foreach($array as $k=>$v) {
		$b[] = strtolower($v[$key]);
	}
	
	print_r($b);
	
	asort($b);
	
	echo '<br />';
	print_r($b);
	
	foreach($b as $k=>$v) {
		$c[] = $array[$k];
	}
	
	return $c;
}

$sorted = val_sort($arr, 'website');
?>

<pre><?php print_r($sorted); ?></pre>

This is just Great!!! Would it be possible to output only two values from array with the last print_r ($sorted); for Ex: name and age ??
