Separating content from style

Folks, I've just learned a bit about Java Beans and how they are useful in separating content from style. They let you do XSLT'ish stuff in your HTML to grab data while not bogging down your HTML with database-related function calls. I've heard this setup referred to as "templates" and "3-tier". It has all kinds of advantages, the biggest of which is probably the ability to specialize: Allow your web-designer to work with HTML/CSS and your DBA to work with SQL, with no overlap. Obviously, PHP doesn't really lend itself to this sort of setup at first. At least, I haven't found a good way to do it. Does anyone have any good docs on how to setup a 3-tier templated system in PHP that separates content from style? If not, how about a few words on this idea? What are your thoughts? How can PHP tackle this problem? advTHANKSance, Dave
