How to convert php seconds to duration?

For example: PHP converts seconds (4490) into hours, minutes and seconds (34:02:02)

To convert seconds into hours, minutes and seconds, PHP provides a function gmstrftime, However, this function is limited to converting seconds within 24 hours. How should we display seconds that exceed 24 hours?

For example, 34:02:02

$seconds = 3600*34 + 122;
function changeTimeType($seconds){
    if ($seconds > 3600){
        $hours = intval($seconds/3600);
        $minutes = $seconds % 3600;
        $time = $hours.":".gmstrftime('%M:%S', $minutes);
    }else{
        $time = gmstrftime('%H:%M:%S', $seconds);
    }
    return $time;
}
echo changeTimeType($seconds);

Result output 34:02:02
