做出来的效果就是上面这样。
代码：
function timeformat($time){ ???$day = $hour = $min = $sec = 0; ???$day ?= floor($time/86400); ???$hour = floor(($time%86400)/3600); ???$min = floor(($time%3600)/60); ???$sec = $time%3600%60; ???$str = ""; ???if ($day) $str.="{$day}天,"; ???if ($hour) $str.="{$hour}小时,"; ???if ($min) ?$str.="{$min}分钟,"; ???if ($sec) ?$str.="{$sec}秒后"; ???return $str;}$time参数为秒数。
