array array_uintersect_assoc ( array $array1, array $array2 [, array $... ], callable $value_compare_func )
Computes the intersection of arrays with additional index check, compares data by a callback function.

$a, mixed $b )Returns:
Returns an array containing all the values of array1 that are present in all the arguments.

array_uintersect_assoc() example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");
