# array_uintersect_uassoc

(PHP 5)

array_uintersect_uassoc — Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions

### Description

array array_uintersect_uassoc ( array `$array1` , array `$array2` [, array `$ ...` ], callback `$data_compare_func` , callback `$key_compare_func` )

Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions Note that the keys are used in the comparison unlike in array_uintersect(). Both the data and the indexes are compared by using separate callback functions.

### Parameters

`array1`

  The first array.

`array2`

  The second array.

`data_compare_func`

  For comparison is used the user supplied callback function. 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.

`key_compare_func`

  Key comparison callback function.

### Return Values

Returns an array containing all the values of `array1` that are present in all the arguments.

### Examples

Example #1 array_uintersect_uassoc() example

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

The above example will output:

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