It doesn't.
It doesn't even differentate between 2 PCs on opposite location on the
globe. You can however get the remote IP-addres (it is stored in $_SERVER).
If you want PHP to differentiate between unique PCs, you need indeed
sessions.

If the browser like cookies: Yes.
Otherwise PHP will try to put the PHPSESSID into the URL, or in the form, or
whatever is available to communicate this.
All these behaviours are depending on the settings in php.ini.
Read more here:
http://www.php.net and type session in the searchbox.
