Php – difference between two arrays

php

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=Array ( [0] => 64 [1] => 98 [2] => 112 [3] => 92 [4] => 92 [5] => 92 ) ;
 $array2=Array ( [0] => 3 [1] => 26 [2] => 38 [3] => 40 [4] => 44 [5] => 46 [6] => 48 [7] => 52 [8] => 64 [9] => 68 [10] => 70 [11] => 72 [12] => 102 [13] => 104 [14] => 106 [15] => 92 [16] => 94 [17] => 96 [18] => 98 [19] => 100 [20] => 108 [21] => 110 [22] => 112);

Best Solution

To get the difference between the two arrays you need to do the following:

$fullDiff = array_merge(array_diff($array1, $array2), array_diff($array2, $array1));

The reason being that array_diff() will only give you the values that are in $array1 but not $array2, not the other way around. The above will give you both.
