Well what level of PHP'ers are you looking at. Is it all, or newbie.
Now i dont really look at tutorials, but you could have suggestions of good books, and maybe some tuts for newbies. As they are the ones mainly looking for tutorials.
Also links to things like the Manual.
and MySQL
maybe the best tutorial of all would be a New Up to date version of learning how to configure Apache and set it all up including PHP and Mysql. To make it easier for people have links to where your version you used in the tutorial.
Other than that, maybe a jobs posting section but i dont think to many will post jobs.
Other than that the site looks pretty good.
