I have 2 arrays A & B - how do I remove items in A that are found in B?

    Do I just sequentially go through each element in B - check for it in A and delete if found or is there another way?

    Thanks.

    $a = array('a', 'b', 'd', 'e', 'f');
$b = array('a', 'b', 'c');	
	
$a = array_diff($a, $b);
