Computes the intersection of arrays, compares data by a callback function.

### 인수

`array1`

  The first array.

`array2`

  The second array.

`data_compare_func`

  The callback comparison function.

  The user supplied callback function is used for comparison. It must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

### 예제

Example #1 array_uintersect() example

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

    Array
    (
        [a] => green
        [b] => brown
        [0] => red
    )
