Edit: Do you have a database? Do you know how to create a table in a db and write/edit/delete entries using PHP?
It would be most helpful if you post the code that you already have so we can help you troubleshoot any SPECIFIC problems that you are having. If you don't have code yet, and are just looking for a direction, then I suggest having a form on one page and process the form on another page that verifies and cleanses the data, writes it to the database, confirms the entry, and automatically redirects user to a page with their information displayed by reading from the database.... (this is just one thought, but there are a LOT of ways you can do it, so the code and your progress are needed ...)
