Re: [PHP] Mozilla user agent escapes detection
Richard, Thanks for responding. http://www.phpguru.org/static/browser.html I may just do that. If it works out for my needs, I'll let you know. Really, right now I'm doing browser detection to simply sort incoming browsers into desktops, bots, and mobile. If I can get your script to do that, then sweet. By the way, another thing I'm trying to do is reliably test to see if a browser accepts cookies. I just looked through your PHP blog, and didn't see that specifically listed, but since I'm emailing you already, may I ask if you have a script that does that? Or a good recommendation? -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

STW? plenty of people offering code that attempts to detect mobile

also I'd offer a link in the top of your site pointing to the mobile site
(and vice-versa) in order to:
1. allow bots to visit both.
2. in case your code guessed incorrectly for some user(s)
I'd also check the UA string specifically for bots first and just let them
through ... they are neither desktop nor mobile browsers.
additionally you might consider how you want to accomodate text browsers
