How do I pattern match using an array of simultaneous candidates?

    $flags = array(
        0 => 'broken',
        1 => 'broke',
        2 => 'fixed',
        3 => 'fix',
        4 => 'update',
        5 => 'glitched',
        6 => 'glitch',
        7 => 'wip',
        8 => 'ok',
        9 => '100 percent',
        10 => '1 to 1'
    );

    $pattern =
'/(?<project>.*)(?<ts>(?<yyyy>[0-9]{4})\-(?<mmdd>[0-9]{4})\-(?<hhnn>[0-9]{4}))(\-)(?<comment>(.*\s|)(?<flag>'.implode('|',$flags).')(\s.*|))(?<ext>\.(7z|zip))/';
