强制 php strtotime 使用 UTC [英] force php strtotime to use UTC

问题描述

我已经看到了一些关于此的问题，但没有明确的答案...当将字符串转换为 unix 时间戳时，strtotime() 将使用为 PHP 设置的默认时区.

I've seen a few questions about this but not a clear answer... strtotime() will use the default timezone set for PHP when converting the string to a unix timestamp.

但是，我想将字符串转换为 UTC 中的 unix 时间戳.既然没有参数，那怎么做呢?

However, I want to convert a string to unix timestamp in UTC. Since there is no parameter for doing so, how can this be done?

我尝试转换的字符串是:2011-10-27T20:23:39，它已经是 UTC.我想将其表示为 UTC 中的 Unix 时间戳.

The string I'm trying to convert is: 2011-10-27T20:23:39, which is already in UTC. I want to represent that as a unix timestamp also in UTC.

谢谢

推荐答案

在调用 strtotime 之前设置系统默认时区:

Set the system default timezone before making the strtotime call:

date_default_timezone_set('UTC');
echo strtotime('2011-10-27T20:23:39')."\n";

// Proof:
print_r(getdate(strtotime('2011-10-27T20:23:39')));

// IMPORTANT: It's possible that you will want to
// restore the previous system timezone value here.
// It would need to have been saved with
// date_default_timezone_get().

查看实际操作.
