在php ex中仅比较日期和月份而无年份。生日 [英] Compare only day and month without year in php ex. birth date

问题描述

我只想将当前日期的日期和月份与订阅日期的日期和月份进行比较。
ex。当前日期（dm）= 3-6 ，我想将其与任何其他 dm

进行比较在php
中，在我的项目条件中，就像我们不比较年份的出生日期。

How should i do it in php In my project condition is like birth date in which we don't compare year.

请帮帮我。

推荐答案

其中的窍门是让月份优先。这样，PHP可以按最大值比较数字。看下面的示例：

The trick in this is to let the month come first. This way PHP can compare the numbers by highest value. Take a look at the following example:

$aDate = DateTime::createFromFormat('m-d', '05-20');
$bDate = DateTime::createFromFormat('m-d', '06-29');

if ($aDate->format('md') > $bDate->format('md')) {
    echo "'aDate' is bigger than 'bDate'";
}
