PHP login system

I need a registration system with mysql database and backend management. The registration contains some general information such as first name, surename, occupation etc with No PASSWORD required. After registration a second page will come out with a link pointed to the user main page, and followed with uid=fad34ls (some random coding) that can be bookmark and access directly afterwards. And the user page will contain some hyperlink as well as some user information in the database. PM me for some more detail.
