Php datetime createfromformat iso 8601

Nobody mentioned to use DATE_ATOM which is as far as i know phps most correct implementation of ISO 8601. It should at least work for the last 3 of these:

format(DATE_ATOM)
);

foreach($dates as $d) {

    $res = \DateTime::createFromFormat(DATE_ATOM, $d);

    echo "try $d: \n";
    var_dump($res);
    echo "\n\n";
}

?>

To be able to parse all of them i wrote a tiny function:

 0) {
        return $success[0];
    }
    return false;
}

// Test
$dates = array(
    "2010-12-07T23:00:00.000Z",
    "2010-12-07T23:00:00",
    "2010-12-07T23:00:00Z",
    "2010-12-07T23:00:00+01:00",
    (new \DateTime("now"))->format(DATE_ATOM)
);

foreach($dates as $d) {

    $res = parse_iso_8601($d);

    echo "try $d: \n";
    var_dump($res);
    echo "\n\n";
}

?>

As @Glutexo mentioned it works only if there are only 1 to 6 precision digits for the decimal part, too. Feel free to improve it.
