How to check if two indexed arrays have same values even if the order is not same in PHP?

Question

I want to compare two indexed arrays as such that values will be same for two arrays but order may differ, for example i tried doing this but it simply doesn\'t work.

Ex

Answer 1

$a = array(1,2,3,4,5);
$b = array(1,3,2,5,3,4);


if(count($a) == count($b) && count(array_diff($a, $b)) == 0){
    echo "A";
}

Need to do a length check or the two arrays above would come out the same.

edit: better solution.
