A session is exactly how it sounds, it keeps track of each users session on your site and is valid for that browser session. If userA logs in then for them $_session['username'] = userA . If userB logs in, $_session['username'] = userB for them. If you want to test this try logging in using Firefox with one username and then log in using a different browser under another username and you'll see how it will work.

Just a note: $_SESSION needs to be written uppercase.

hi
meaning of your answer this is?
variable session with the same name for server is unique ?
does the server identify different user with this variable session with the same name?
thanks very much for all your trouble

Each session is unique to the person browsing the website.
