Opmerking: > In order for this to work, your configuration setting in php.ini must point to the correct location of the file on your system. browscap

 is not bundled with PHP, but you may
find an up-to-date  file here.

php_browscap.ini

While contains information on many browsers, it relies on user updates to keep the database current. The format of the file is fairly self-explanatory.
