Found on php.net maybe this will be useful:

$_POST = array();
$str = 'first=value&arr[]=foo+bar&arr[]=baz';
parse_str(html_entity_decode($str), $_POST);
print_r($_POST);

Array
(
    [first] => value
    [arr] => Array
        (
            [0] => foo bar
            [1] => baz
        )

)

Note:

The magic_quotes_gpc setting affects the output of this function, as parse_str() uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables.
