PHP attaching css and JS files to current page

Hi, is there a way how a PHP class can attach JS (javascript) and CSS documents to current web page in which the class is instanced ? till now i used an "echo" which "write" a <script></script> code into current document. in this javascript, i used to have a createElement function to attache C\other CSS or JS file. it's not so clean and maybe a better possibility exists. Thanks to let me know. -- Alain ----------------------------------------------------------- Windows XP x64 SP2 PostgreSQL 8.3.5 / MS SQL server 2005 Apache 2.2.10 PHP 5.2.6 C# 2005-2008
