    next($num); next($age); echo current($num) . " : " . current($age) . "<br>";
    next($num); next($age); echo current($num) . " : " . current($age) . "<br>";
    next($num); next($age); echo current($num) . " : " . current($age) . "<br>";
    next($num); next($age); echo current($num) . " : " . current($age) . "<br>";
    next($num); next($age); echo current($num) . " : " . current($age) . "<br>";
