Can someone direct me to a good PHP login / user registration tutorial? I know i get many results if i simply Google it but i'm looking for something that maybe someone has used and found to be useful and reliable.
The main trouble i'm having is actually maintaining a session site-wide, rather than just the one page. I also haven't yet approached the concept of a session timeout.
Any help / advice / links would be appreciated.
EDIT: More than just code, i'm looking for something that will step me through the process so that i can understand it rather than just pasting blocks of code.
