检查给定日期是否过去 [英] Check if a given date is past

问题描述

我有一个星期的日历，举行事件，并希望用户不能添加事件在过去几天。所以我正在使用这样的功能：

I have a week calendar that holds events, and want that users can't add events for the past days. So I'm tring to use a function like that:

if( strtotime($this->day) < time() ){ // date format is YYYY-MM-DD
// date is past 
}else{   
// date is not past
}

似乎工作正常，除了它将今天视为过去一天。我做错了什么？

It seems to works fine, except that it consider today date as a past day. What am i doing wrong?

推荐答案

时间戳记永远不会包含日期，但始终为当前第二个。 strtotime（$ this-> day）将在 0:00 返回今天的日期，而您正在比较你现在可以使用 11:12 。

A timestamp never contains only the date, but is always down to the current second. strtotime($this->day) is going to return today's date at 0:00, while you are comparing it against now, say, 11:12.

你可以使用 strtotime（ $ this-> day 12:59:59 pm）; （如果 $ this-> day 的格式允许）使用明天的时间戳。

You could use strtotime("$this->day 12:59:59pm"); (if the format of $this->day allows for that) or use tomorrow's timestamp.
