如何在PHP中以秒为单位获得时间差异? [英] How to get difference of a time in seconds in PHP?

问题描述

我有一个数据类型为time"的数据库列，它存储 11:30:45.这次我在一个变量中提取了

I have a database column with datatype "time" which stores 11:30:45. I have fetched this time in a variable say

$databasetime = 11:30:45

我想声明一个变量，比如 $currenttime，它将包含刚才的时间.就像现在的 11:33:30 一样，另一个变量将包含它们之间的差异，如

I want to declare a variable say $currenttime which will contain time just now. Like its 11:33:30 right now and another variable which will contain their difference in seconds like

$timediff = $currenttime - $databasetime;
echo $timediff;

我正在尝试 $currenttime = time(); 但我没有得到我想要的结果.我想要 $timediff = 165 但是当我回显 time() 时，我得到了一个非常大的值.

I am trying $currenttime = time(); but I am not getting the result which I desire. I want $timediff = 165 but when I echo time(), I am getting a very big value.

推荐答案

$databasetime = strtotime('11:30:45');
$curtime      = time();
echo $curtime - $databasetime;
