PHP: Use htaccess to speed up your website

What have i done is use the gzip module of the apache server by using php and a .htaccess file. I believe this is one of the most nice ways to take advantage of this feature without making any changes to your website. What it does is adding lines of code at the beginning of txt/html/htm/php files, css files and js files. After we do this we add a closing line at the end and we are good. Gzip is in place up and running.
