Is it possible to check a users browser and then switch the doctype depending on which browser they are using?

I'm working on a site that displays perfectly in Firefox and Netscape using strict XHTML, but completely messes up in IE6. To get it working properly in IE6 the doctype has to be transitional HTML 4.01.

Yes, I'd use Server-Side code; what <i>Server Model</i> (ASP, PHP, CF, JSP) are you using?

PHP.

Actually, I think I was wrong in saying that the site displays perfectly in Firefox and Netscape. The only reason they display correctly is because they are switching to Quirks mode (which I guess means they won't validate) whereas IE6 is staying in Standard mode, so IE6 is kind of doing the right thing and it's my coding that's wrong... I think...

... does that make sense?
