How to enable website login access of one website to another website

[abubakar madni]

Hello,

I am not a php guy.

what I want to know about is as under

I have two different scripts installed at separate sub-domains

Now I want that user of one script should be able to get login at other with the same login data.

or in other words once you register you may have access to all scripts or websites.

in my case one is classified script and the other is file sharing script.

both being at one place does not make sense but I installed both for test purpose only.

also if you can please let me know how more than two databases or scripts can be attached in terms of login

***** I am not a developer or programmer ***** please answer as I am newbie to mysql data bases
