Problem installing PHP 4.0

I'm the webmaster of the intranet site of a French company. I want to use Php 4.0, because I think it's a simple and very good language. I use a Apache server but, after many tryings, it couldn't make the incrementation when PHP is a DSO object. The problem is : next I installed PHP, my scripts appear, and are appearing too the HTML balises (<HTML>, <HEAD>, </HEAD>...). I don't know how I can do.
