Here is a tip that fits well with this tutorial:
There have been rumors that search engines treat urls ending with .php differently than .html. Not sure if thats true but if that bother you then make a .htaccess file to a directory where your .php scripts are and then put these lines into this file:
Code:
RewriteEngine on
RewriteRule (.*).html$ $1\.php
now you can write filename.html instead of .php, mod_rewrite will change the .html part to .php for you
