Browser.ini

So i've been trying to use get_browser() on my website to test something, and I've been looking at the documentation on php.net (http://us2.php.net/manual/en/function.get-browser.php) and one of the comments mentions taking info from php_browsercap.ini (grabbed from http://www.garykeith.com/browsers/downloads.asp presumably) and putting into browsercap.ini to fix the parsing error messages.

But I'm not sure where I'd put the php_browsercap.ini file in my directory.

Any help would be appreciated.

Thanks!
