Optimized CSS via PHP
I’m putting together a really tight little todo list manager right now, and in the process I’ve been exploring some simple things on my … todo list. Hrm, that came out weird.
Anyway, I wanted to manually handle minifying and organizing my CSS files. I wanted three important things:
- The CSS files, no matter how many, should be served up from a single HTTP request
- The CSS contents should be stripped down to take out unnecessary whitespace and comments
- The whole request should be properly gzipped
I found most of what I needed in a really cool little blog post(post removed), but it needed a lot of surgery. Take a look.
I set my compression up with ob_gzhandler, and do a little magic with the headers. Cache expires in a day, which I think is plenty often enough, but feel free to tweak to your own needs.
Next I set up an array of CSS files. Notice they’re all real CSS files, not PHP files in disguise. I kept things simple. They’ll be read into PHP and cleaned up in the bottom section. Simple, right?
Oh, right… you can use it in your HTML just like you would a normal CSS file:
<link rel="stylesheet" type="text/css" media="screen" href="css/styles.css.php" />
It may not be as robust as Google Minify (though I’m stealing pieces of it), but it’s tiny and mine. Victory!
