Of course you can. PHP is a programming language, not a pocket calculator.
;-)

www.php.net is the place to be for learning about the language.
Scout around a little and look things that might interest you.

This part covers control structures, like the one you are looking for:
http://nl3.php.net/manual/en/language.control-structures.php

Also, if you need to redirect to another site, use:
header("Location: www.example.com");
exit;

(Do not forget the exit, since PHP will continue executing code after the
header.)
