Anchors

Last checkin to bring back https://github.com/codeguy/php-the-right-way/pull/309

Next (but I'd prefer waiting until everything is integrated to make both our lives easier, if you still want the changes), I'd like to break the Database section into sub-posts, break the Resources section into subsections as well (it's only partly done) and then fix the anchors / highlighting for welcome / credits

Hope this helps and that all of these commits are clearer to integrate

Thanks
