array_udiff_uassoc

Computes the difference of arrays with additional index check, compares data and indexes by a callback function

array **array_udiff_uassoc** array $array array $arrays callable $value_compare_func callable $key_compare_func

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

Note that the keys are used in the comparison unlike and . array_diff``array_udiff

arrayThe first array.

arraysArrays to compare against.

value_compare_func``key_compare_func The comparison of keys (indices) is done also by the callback function . This behaviour is unlike what does, since the latter compares the indices by using an internal function. key_compare_func``array_udiff_assoc

Returns an containing all the values from that are not present in any of the other arguments. array``array

Voorbeeld: example

<?php
class cr {
    private $priv_member;
    function __construct($val)
    {
        $this->priv_member = $val;
    }

    static function comp_func_cr($a, $b)
    {
        if ($a->priv_member === $b->priv_member) return 0;
        return ($a->priv_member > $b->priv_member)? 1:-1;
    }

    static function comp_func_key($a, $b)
    {
        if ($a === $b) return 0;
        return ($a > $b)? 1:-1;
    }
}
$a = array("0.1" => new cr(9), "0.5" => new cr(12), 0 => new cr(23), 1=> new cr(4), 2 => new cr(-15),);
$b = array("0.2" => new cr(9), "0.5" => new cr(22), 0 => new cr(3), 1=> new cr(4), 2 => new cr(-15),);

$result = array_udiff_uassoc($a, $b, array("cr", "comp_func_cr"), array("cr", "comp_func_key"));
print_r($result);
?>

Array
(
    [0.1] => cr Object
        (
            [priv_member:cr:private] => 9
        )

    [0.5] => cr Object
        (
            [priv_member:cr:private] => 12
        )

    [0] => cr Object
        (
            [priv_member:cr:private] => 23
        )
)

In our example above you see the pair is present in both arrays and thus it is not in the output from the function. Keep in mind that you have to supply 2 callback functions. "1" => new cr(4)

Opmerking: > Please note that this function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using, for example, . array_udiff_uassoc($array1[0], $array2[0], "data_compare_func", "key_compare_func");
