Get values which only occur in one of two flat arrays
array-difference, arrays, php
Solution
Note: this answer will return the values in `$array2` that are not present in `$array1`, it will not return the values in `$array1` that are not in `$array2`.
$diff = array_diff($array2, $array1);
`array_diff()`
Problem
I have following two arrays. I want the difference between these two arrays. That is, how can I find the values that do not exist in both arrays? ``` $array1 = [64, 98, 112, 92, 92, 92]; $array2 = [3, 26, 38, 40, 44, 46, 48, 52, 64, 68, 70, 72, 102, 104, 106, 92, 94, 96, 98, 100, 108, 110, 112]; ```
