Getting unique values from 2 arrays

Question

I have 2 arrays that I\'m trying to get the unique values only from them. So I\'m not just trying to remove duplicates, I\'m actually trying to remove both duplicates.

Answer 1

Another good solution is this:

$array1 = array(10, 15, 20, 25);

$array2 = array(10, 15, 100, 150);

$output = array_diff(array_merge($array1, $array2), array_intersect($array1, $array2));

// $output will be (20, 25, 100, 150);
