PHP minify

Combines, minifies, and caches JavaScript and CSS files on demand to speed up page loads.

Minify is a PHP5 app that helps you follow several of Yahoo!'s Rules for High Performance Web Sites.

It combines multiple CSS or Javascript files, removes unnecessary whitespace and comments, and serves them with gzip encoding and optimal client-side cache headers.
