The only known problem here is that, if a HTTP_USER_AGENT string does not contain the operating system, it will be identified as Unix. For unknown browsers, this may not be correct. For browsers, it should correctly identify all versions of: Amaya Galeon iCab Internet Explorer For AOL versions it will identify as Internet Explorer (AOL) and the version will be the AOL version instead of the IE version.

Para usar a class faça um include do arquivo com a chamada

<?php include("arquivo-da-class.php"); $br = new Browser; echo "$br->Platform, $br->Name version $br->Version"; ?>
