Prize amount increased: off-the-shelf solution for creating PHP site with user accounts, logins, and db-populated tables?

Given that there are so many sites which reuse the same functionality: - user creates an account with an associated email address (and must optionally click a link in an email to confirm their account) - user signs in and signs out of the site - while signed in, user views a page where the back end does a database query, to find all rows in a given table associated with that user, and then populates an HTML table with all the resulting rows (e.g., a user clicks a page to view products they have flagged as one of their 'favorites') Is there an off-the-shelf solution that lets you rapidly create a bare-bones site with all of this functionality already built in -- creating accounts, signing in -- and simple instructions for things like 'how to get a list of all records from a table associated with this user's id, and display them in an html table'? And then the webmaster can just customize it with their site's design, and with the specific functionality that they want the site to embody. (That's right, you don't have to do any actual programming for me, just point me in the direction of an off-the-shelf solution that makes it easy to do this.) Extra points for: a free or cheap solution, a solution that does most of what I want, and a solution that comes with good tutorials for getting a new login-based site up and running quickly. (And I usually send tips to anyone who provides useful information even if I end up picking another contest winner.)
