array_diff_uassoc

Computes the difference of arrays with additional index check which is performed by a user supplied callback function (PHP 5)
array array_diff_uassoc ( array array1, array array2 [, array ..., callback key_compare_func] )

Example 240. array_diff_uassoc() example

The "a" => "green" pair is present in both arrays and thus it is not in the ouput from the function. Unlike this, the pair 0 => "red" is in the ouput because in the second argument "red" has key which is 1.

<?php
function key_compare_func($a, $b)

{

    if ($a === $b) {

        return 0;

    }

    return ($a > $b)? 1:-1;

}

$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result = array_diff_uassoc($array1, $array2, "key_compare_func");
print_r($result);
?>

The above example will output:

Array

(

    [b] => brown

    [c] => blue

    [0] => red

)

The equality of 2 indices is checked by the user supplied callback function.
