如何检查当前日期/时间是否超过了设定的日期/时间? [英] How can I check if the current date/time is past a set date/time?

问题描述

我正在尝试编写一个脚本来检查当前日期/时间是否超过 05/15/2010 下午 4 点

I'm trying to write a script that will check if the current date/time is past the 05/15/2010 at 4PM

如何使用 PHP 的 date() 函数来执行此检查?

How can I use PHP's date() function to perform this check?

推荐答案

自 PHP >= 5.2.2 起，您可以使用 DateTime 类:

Since PHP >= 5.2.2 you can use the DateTime class as such:

if (new DateTime() > new DateTime("2010-05-15 16:00:00")) {
    # current time is greater than 2010-05-15 16:00:00
    # in other words, 2010-05-15 16:00:00 has passed
}

传递给DateTime构造函数的字符串被解析根据这些规则.

The string passed to the DateTime constructor is parsed according to these rules.

请注意，也可以使用 time 和 strtotime 函数.查看原始答案.

Note that it is also possible to use time and strtotime functions. See original answer.
