Rewriting for SEO-Friendly URLs: .htaccess or PHP?

Modern database driven web sites implement SEO-friendly URLs emulating static directories and files. Switching to such “clean” URLs enables good indexing by search engines, makes URLs more user-friendly and hides the server-side language. For example, this clean URL may refer to the page in some product directory:

http://somesite.com/products/network/router.html

In fact, there is no /products/network folder on the server and no router.html file at all. The page is generated by server script using database query for “network” product category and “router” product. But who calls the script and where it gets the query parameter values?

This technique is usually referred as “URL rewriting”. It allows web server to recognize what information was requested by parsing the URL string. Apache and PHP allow multiple options to implement URL rewriting. So which one is the best?
