This is not possible with PHP.
PHP is a server-side language and in most cases (the server) is provided with little or no information about the client's machine requesting information. That is to say little beyond what is offered in various $_SERVER variables like $_SERVER["HTTP_USER_AGENT"], or $_SERVER['REMOTE_ADDR'] and other such variables.
To see what information is available run a PHP info script.
<?php
phpinfo();
?>
This is, however, possible on the client-side using JavaScript.. once gathered it can then be passed to PHP.
