Opposite of array merge in PHP
<p>Ok, two arrays:</p>

<pre><code>$first = array(1,2,3,4,5,6,7,8,9,10);
$second = array(1,2,3,4,5);
</code></pre>

<p>Is there a way (without looping through them if it can be helped) of doing an array_merge style function where it returns this array:</p>

<pre><code>$new = array(6,7,8,9,10);
</code></pre>

<p>Where if it finds a match, it does not return it.</p>
