Once again, someone has popped up offering completely free PHP/MySQL hosting. I'm still not sure how they plan to pull it off, but hey - get it while it lasts!
They offer a pretty flexible package and even will throw in a healthy dose of MySQL for ya. The limit on space is about 20MB, but it's flexible too. Oh, and there's no FTP access - it's all web uploads. So, what are you waiting for? Go get some space now!
