Be careful about HTML generated by client-side scripts (e.g., Javascript) because, since they depend on the browser, Googlebot (and other spiders) may not be able to spider them.
One reason is that you can make a .html file execute as php. Or a directory like www.xxx.com/yyy can execute as php.
You don't have to make these changes, google will index www.xxx.com/yyy.php?a=b&c=d.... perfectly.
Be careful, don't add to many variables at the end. Especially not sessionids and other dynamic variables. The robots don't want to get into an endless loop.
