mysql & php help!

well, u can either use some framework (many of them have nice tutorials how to make some basic with ease, try http://cakephp.org/ , its rly simple and they have tutorial in "cookbook" exactly for what u need) or just use google, there are actually shitloads of articles on how to work with mysql, cookies/sessions and so on, putting like 3 articles with code examples together should be enough to have a functioning webpage with all what u need. But I would go for that cake php framework if I was you.

You should first get the basics of php/mysql and start with some easy stuff. Otherwise you start running before walking. I'm not saying it's a bad thing, but it doesn't really help you to code something using frameworks or codesnippets when you don't know what function x or y is actually doing. IMO frameworks are the worst things to start with... they're there to save more experienced coders time and work. Using them properly often requires atleast the very basic knowledge...

The most important thing (imo) is, to understand what actually is happening in your code, so i would suggest you to start with some newbie tutorials and advance step by step.

Personally http://tut.php-quake.net/en/ helped me a lot when i started with php/mysql. Easy to understand and covers the most important things to start with.

Smells like CMS
