How to access variables in phpinfo()?

Hello, Total newbie... As a footer I want something like: "Running with Apache 1.3.12 / PHP 4.0.2 and MySQL 3.22 on Windows NT 5.0" I see most variables in phpinfo(), but how do I access them all? Ok, enivironment vars like SERVER_PROTOCOL are easy, but how about the other vars like, e.g. the first one: system. Or the PHP version? MySQL version? And so on... Thanks!
