<?phpfunction cTime($seconds){if($seconds<60){$msg=$seconds."秒";}elseif($seconds<3600){$msg=(int)($seconds/60)."分";}elseif($seconds<86400){$msg=(int)($seconds/60/60)."小时";}else{$msg=(int)($seconds/60/60/24)."天";}return $msg;}?>

调用方法：

<?php$addtime = time();$seconds = $addtime - $rswy['addtime'];echo cTime($seconds);?>
