如何获取我的css文件的最新修订日期?

Situation: My CSS was getting cached which was really annoying so I solved it this way

<link rel="stylesheet" href="/css/screen.min.css?{$smarty.now}" type="text/css" />

But now it reloads it every single time, what I want now is to only reload when there are changes.

So, what I was thinking was instead of {$smarty.now} use something that gives me the latest revision date/time.

Question:
How do I get the latest revision date/time from my css file with php/smarty/javascript?

    You could use php's filemtime(). This function will get the last modification time of your file, which wouldn't change unless changes were made to the file.

    You would do something like:

    <link rel="stylesheet" href="/css/screen.min.css?{$filemtime("/css/screen.min.css")}" type="text/css" />
    

    The first forum item for this function in the documentation is a exact solution for your problem.
