hi friends in the last two posts I did't mention my exact problem so here it is.
The problem i am facing is i am creating a loggin system to my site by assining a unique id to each users.
such that a user can't login from two places.
In ASP I can store a variable(an array or "sripting.dictionary" object) as an application variable
I can check the existence of the user id in this array before allowing a user
to loggin.
and don't allow the user to loggin if the id is already present in the array.
I want to do the same in php
how can I do it.
login problem
