PHP compare array

Question

Is there anyway to compare arrays in php using an inbuilt function, short of doing some sort of loop?

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

if (array_are_         


        

Answer 1

A speedy method for comparing array values which can be in any order...

function arrays_are_same($array1, $array2) {
    sort($array1);
    sort($array2);
    return $array1==$array2;
}

So for...

    $array1 = array('audio', 'video', 'image');
    $array2 = array('video', 'image', 'audio');

arrays_are_same($array1, $array2) will return TRUE
