php - array_uintersect_assoc

Description

array array_uintersect_assoc ( array $array1, array $array2 [, array $ ..., callback $data_compare_func] )
array_uintersect_assoc() returns an array containing all the values of array1 that are present in all the arguments. Note that the keys are used in the comparison unlike in array_uintersect(). The data is compared by using a callback function.

Example 278. array_uintersect_assoc() example
<?php

$array1
= array("a" => "green", "b" => "brown", "c" => "blue", "red");

$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");
print_r(array_uintersect_assoc($array1, $array2, "strcasecmp"));

?>

The above example will output:
Array
(
   [a] => green
)
