best way for PHP page

Hi, i would like to improve my coding quality when i use PHP code and for that i would request your help. in my web developer experience, i have to confess that i've never succeeded in spliting PHP code from HTML code. i mean that all my web pages consist of PHP code mixed with HTML code (for rendering pages). Some developers tell it's possible to write only PHP code for web page. i agree with them but only when those PHP pages do not render web elements (write text, display pictures, display formular, ...). the purpose of my post is to know if i can really (at 100%) split client code (display images, write text,...) from server code (move or copy data to DB, create connection objects,...) so what do you think about that ? -- Alain ------------------------------------ Windows XP SP2 PostgreSQL 8.2.4 / MS SQL server 2005 Apache 2.2.4 PHP 5.2.4 C# 2005-2008
