Re: php,mysql,html question

You need to use .php so that the web server feeds to the mod_php module the .php file so that mod_php can execute the php code in it. You could change things so that all files are given to the mod_php module to interpret, so that you could use php code in .html files, but that would slow down your web server (unless most of your .html files have php code in them). I haven't tried it yet but I think there's a way using Apache's mod_rewrite to make the .php files look like .html files to the user.
