PHP - 准确的Unix时间戳[关闭]

Question

I'm trying to create an accurate Unix timestamp to assign to a variable, based on different time periods. Any idea how these timestamps periods can be calculated?

Answer 1

I could only suggest to you to read the time Manual.

http://php.net/manual/en/function.time.php

Today to last midnight -> Get Hours + Minutes, do a Minus 24:00 hour calculation, use http://php.net/manual/en/function.abs.php to get your value positive

All the others are solvable by using http://php.net/manual/en/function.strtotime.php

In the worst case convert it to unix time and get the difference, you will have an accurate output without paying any attention to the leapyears and other time conditions which you have mentioned like the 28/29 feb problem.
