Possible Duplicate:Should I use a file extension or not? My current hosting provider does not let me put PHP code inside of a .html page.So part of my content is in a database and displayed with PHP, but most of it is in pre-rendered .html files.I'd like to put more of it in .php files however I am concerned that search engines will penalize my .php pages because they are PHP.Is there any evidence so that effect?Thanks.
Does Google treat .html pages differently from .php pages?
google;php;html;search engines
