Comparing Arrays.

[Napster]

I cannot seem to find this answer by googling it, nor could I find a function on php.net but is there an easier way to compare arrays than the following?

$a1 = array(1, 2, 3);
$a2 = array(1, 2, 3);

if ($a1[0] == $a2[0] && $a1[1] == $a2[1] && $a1[2] == $a2[2]) eco "The array's are the same";  

Thank you.

if($a1 === $a2) echo "The arrays are the same.";

Good reference, I didn't know about that page. Here's a quick link: [man]language.operators.array[/man]

There are a plethora of Array Functions that can be used to compare arrays in all sorts of ways beyond that of === if you require
