Hello,
Below is code I hacked up to read a user agent string (i.e. Mozilla/5.0 (Windows; U;
Windows NT 5.0; en-US; rv:0.9.8) Gecko/20020204
) and return several items including:
- the browser name,
- the browser version,
- the browser's major version number, and
- user definable compatibility listings.
This post is attached so that others may benefit. DISCLAIMER: I've been working with
PHP for a few months... about as long as I've ever been programming - feel free to
trust my brain at your own risk. Your thoughts and suggestions are welcome. :-)
ASSUMING CORRECTIONS ARE MADE DUE TO MAILING-LIST COMMENTS, I WILL REPOST THIS CODE.
Cheers, Rob
P.S. Is this the correct forum for tossing code around?
Now for the code...
WEB PAGE: (*.php ) <-- I removed all the HTML for readability.
