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;
}
使用方法如下：
复制代码 代码如下:
$seconds = 3712;
echo changeTimeType($seconds);
