array_udiff_assoc

Computes the difference of arrays with additional index check, compares data by a callback function (PHP 5)
array array_udiff_assoc ( array array1, array array2 [, array ..., callback data_compare_func] )

Example 280. array_udiff_assoc() example

copy to clipboard

<?php
class cr {

    private $priv_member;

    function cr($val)

    {

        $this->priv_member = $val;

    }


    function comp_func_cr($a, $b)

    {

        if ($a->priv_member === $b->priv_member) return 0;

        return ($a->priv_member > $b->priv_member)? 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),);

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

The above example will output:

Array

(

    [0.1] => cr Object

        (

            [priv_member:private] => 9

        )


    [0.5] => cr Object

        (

            [priv_member:private] => 12

        )


    [0] => cr Object

        (

            [priv_member:private] => 23

        )

)
