Answer 2

For PHP, try Minify: http://code.google.com/p/minify/

From the docs:

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.
