[solved]Use friendly URL: How to give a file the suffix ".php" instead of .html?

Does anybody know how I can give a document the suffix ".php" instead of ".html" by using the "Use friendly URL"-function?

Is it possible to define a Content Type with the suffix .php? I think this could solve the problem, because MODx always use the Content-Type as suffix.

Does anybody know if this is possible?

OK. It was pretty easy. Found it by myself. Just click on System->Content Types :):):)
