Php And W3c Validation

Php And W3c Validation
Hi,

Project is just easy manual work for those who know php.

I have a site that needs the following done to it:

1. Make each page have it’s own .php page, currently it’s a dynamic index.php?i=prices, but needs to be prices.php
2. Header is incorrectly configured, it has a central header which puts the same title for each page (not good for seo), so each page has to have it’s own title, and only universal items appear in a header.php. (like site.css)
3. Not necessary, but wanted to make it w3c valid (http://validator.w3.org/)

About 30 pages in all.
