Best automated Registration Login/Out for Websites

[didzmad]

Hello all,
I am looking to implement a new feature on my website.
I would like to get a log in form that would take the members to an update page where they can update their details showing on my website

Here are the features I need:
- Log IN/OUT Function
- Update Page
- Possibility to Upgrade their membership to unlock some of the advanced listing
- Automated Lost Password/Reset Password button

I have asked google but too many options and did not really compare any.
What do you use? What do you think is the best? Where should I concentrate my research?

Regards
Didzmad

This will not be done using JavaScript, well, maybe the AJAX part, but not the database logic which is the main stuff you need.

You will need to look into PHP or ASP.Net.
