php问题...如何检查某事是否在两个值之间？ [英] php question... how to check if something is between two values?

问题描述

我知道我在这里很容易遗漏一些东西...我一直在尝试不同的运营商，但是没能找到这个...

I know I'm missing something easy here... I've been trying different operators, but haven't been able to figure this out...

如何查看当前日期是否介于两个其他日期之间？

How do I go about checking to see if the current date is between two other dates?

因此，如果我的日期为2010年2月2日， to date of 2/10/2010，如果当前日期（2/4/2010）落在这两个日期之间，如何返回TRUE？

So, if I have a from date of 2/2/2010 and a to date of 2/10/2010, how can I return TRUE if the current date (2/4/2010) falls between those two dates?

推荐答案

要进行这样的比较，您需要进行单独的比较。如果$ d是您要比较的日期，则$ d1是较早的日期，而$ d2是较晚的日期，则为：

To do a comparison like this you need to do separate comparisons. If $d is the date you want to compare, $d1 is the earlier date, and $d2 is the later date, it would be something like:

if ((strtotime($d) > strtotime($d1)) and (strtotime($d) < strtotime($d2))) {
    return true;
} else {
    return false;
}
