PHP, HTML, CSS and a lot of problems

I have written a short script in PHP that parses an HTML template and replaces Blocks (looks-like special HTML Tags) with information fetched from a Mysql database. The problem I have is that the HTML template includes several Javascripts and CSS definitions, looks like that: <link rel="stylesheet" type="text/css" href="default.css"> <style type="text/css">@import url(default.css);</style> I do not understand why the browser cannot interpret it after it is parsed through the PHP script. A link relation to a favicon works without problems and is displayed in the browser URL. Does anybody know how to get it running?
