Simple File Cache Updating

Have aggressive caching on your server or framework? Have issues with clients seeing changes when you update a file or image? Well, you're in luck! Prevent aggressive browser cachinbg with this class.

Just instantiate the class and wrap your files with the method. Like magic!

$cache = new cache(__DIR__);

<!-- Example -->
<link rel="stylesheet" href="<?=$cache->file('/styles/main.css');?>" />

The output will look something like this...

<link rel="stylesheet" href="/styles/main.css?version=1476374736" />

Now everytime you edit/update your file or image it will grab the file's filemtime and append it to the end of the file with a query string, assuring you that the browser will download the "new file" anytime it's updated.

So damn good that you'll say, "Thanks Obama".
