array_uintersect_assoc — Computes the intersection of arrays with additional index check, compares data by a callback function

Description

array_uintersect_assoc ( array $array , array ...$arrays , callable $value_compare_func ) : array

Computes the intersection of arrays with additional index check, compares data by a callback function.

Note that the keys are used in the comparison unlike in array_uintersect(). The data is compared by using a callback function.

Parameters

array

The first array.

arrays

Arrays to compare against.

value_compare_func

The comparison function 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.

callback ( mixed $a, mixed $b ) : int

Return Values

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

Examples

Example #1 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
)
