Me: What does function session  (ip, user_name,password) mean ??

John: It mean,

.

if (ip != "")

{

if (user_name !="")

{

if (password !="")

{

build up a session or cookie ();

}

}

}

.

John: Hackers change the function session ("ip", "user_name", "password") into function session ("ip");

.

That mean,

.

if (ip != null)

{

build up a session or cookie ();

}
