如何发现今天的日期是否在其他2个日期之间？ [英] How to discover if today's date is between 2 other dates?

问题描述

我无法正确理解语法，我只需要一个IF语句来检查今天是否在一组日期之间，如果是，则回显。该如何调整？

I can't quite get the syntax right, I just need an IF statement to check if today is between a set of dates and if so, echo. How should this be tweaked?

$now = time('Y/m/d');
$date_september = '2014/09/01';
$date_october = '2014/10/01'; 

if ($now > $date_september && $now < $date_october) 
{
    echo "do this...";
}

推荐答案

1. 使用 DateTime（）。它使日期比较更容易，因为这些对象具有可比性。


2. 您的如果语句无效。 PHP不支持任何比较的简写语法。

1. Use DateTime(). It makes date comparisons easier as those objects are comparable.
2. Your if statement is invalid. PHP doesn't support any shorthand syntax for comparisons.

试试这个;

$now            = new DateTime();
$date_september = new DateTime('2014-09-01');
$date_october   = new DateTime('2014-10-01'); 
if ($now > $date_september && $now < $date_october) {
    echo "do this...";
}
