With help of the ip number, you can always get the country/isp with quereing
data from a relevant database.

$_SERVER['REMOTE_ADDR']

No, PHP is a serverside script language, and do not know anything about the
remote client, more than what is sent with the browser data.

You need to use client side scripts like javascript and somehow make it to
send the data to your server.

The $_SERVER['HTTP_USER_AGENT'] usually will include the operating system of
the machine where the browser is run. Some people has made their browser to
not send this information.

Usually you need the client to submit the data to the server, by using form-tags.

Me either, lol.
I have seen a counter though using PHP, you save a .txt file that contains a number, 0, then use PHP to read the file, add one to the value and save it then display the value on the page.

Look here: A simple hitcounter
