Hello. This is my first post in the forums , but anyways...
I'm planning to make my new website, Below Zero Network, out of PHP. I've heard there are PHP Databases, but I can't find any information on these databases. Anyone help me here?

Also, wheres a page that helps you with forms? I mean like, example: "staff.php?id_erik". The page, with the ID code or something at the end. Where do I learn how to do stuff like that? Thanks in advance

PS: If anyone wants to see a beta of my layout, its right here: http://below-zero.hypermart.net/bzn/
