compare difference in nested numeric array | |

You can define a custom comparison function using array_udiff(). function udiffCompare($a, $b) { return $a['ITEM'] - $b['ITEM']; } $arrdiff = array_udiff($arr2, $arr1, 'udiffCompare'); print_r($arrdiff); Output: Array ( [3] => Array ( [ITEM] => 4 ) ) This uses and preserves the arrays' existing structure, which I assume you want.ref: http://stackoverflow.com/questions/11821680/array-diff-with-multidimensional-arrays | |
