Hello,
I am trying to develop a little application in PHP, but I need your help.
When a user open an account or login, some information should be stored in his/her computer (cookies). And then if he/she logged out and try to open another account it should dipaly the message: "Ouuu you already have one account!".
That's all.
I have done that by checking real IP, but I do not know how to do that using cookies.
waiting for your help
