that's a pretty general question. i assume by how much you are here that you know that many people will help you.
help you learn and understand .. not really code entire scripts for you.
do you know some php? do you know how to connect to a database?
if you answered yes, then just post more specific questions in places where you are getting stuck .. if you answered no to either of those, then you might want to practice php a little more before you make a commitment like that to your teacher.
there are always places like
www.hotscripts.com where you can find pre-generated code, but you would still need to customize it to your requirements.
