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

As far as I can tell, there isn't a single built-in function that'll do it for you, however, something like:

if (count($a) == count($b) && (!count(array_diff($a, $b))) {
  // The arrays are the same
}

Should do the trick
