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

Conclusion from the commentary here:

Comparison of array values being equal (after type juggling) and in the same order only:

array_values($a1) == array_values($a2)

Comparison of array values being equal (after type juggling) and in the same order and array keys being the same and in the same order:

array_values($a1) == array_values($a2) && array_keys($a1) == array_keys($a2)
