I want to download a website that uses php to generate its pages. If I use

wget --convert-links --mirror --trust-server-names the_website.com

the php files are downloaded as php files. When I open the webpage locally, FF gives me a popup box asking whether I want to open the php file of a page with gedit.

Is there any way to download a full web page as plain html so that I can access them in a browser locally?
