Browser Detection with PHP
Browser detection is an illusive task that is ultimately doomed to fail. Browsers are always changing and keeping up to date with these changes is a continuous job. Some browsers allow the user to alter the way the browser identifies itself, or to not identify itself at all. Some firewalls block the sending of the browser identification, so no browser detection scheme is entirely successful.
Since browser detection is so unreliable, I am no longer maintaining this script.
