计算两个时间差并返回差多少天,时,分,秒

本函数实现两个unix时间戳的差，并返回两个时间戳相差的天、小时、分、秒，精确到秒，两个参数都是时间戳，虽然代码很简单，但是很实用。

function timediff($begin_time,$end_time)

{

if($begin_time < $end_time){

$starttime = $begin_time;

$endtime = $end_time;

}

else{

$starttime = $end_time;

$endtime = $begin_time;

}

$timediff = $endtime-$starttime;

$days = intval($timediff/86400);

$remain = $timediff%86400;

$hours = intval($remain/3600);

$remain = $remain%3600;

$mins = intval($remain/60);

$secs = $remain%60;

$res = array("day" => $days,"hour" => $hours,"min" => $mins,"sec" => $secs);

return $res;

}
