It's really none of your business what OS I'm running :-v You may be able to make an educated guess from the HTTP headers in $_SERVER. var_dump($_SERVER); and see what you get. But you can't RELY on them, as some users will intentionally mask/alter that. If your website depends on the visitor's OS for anything other than trivial behaviour, you're in real trouble. _______________________________________________________ The information in this email or in any file attached hereto is intended only for the personal and confiden- tial use of the individual or entity to which it is addressed and may contain information that is propri- etary and confidential.
