We are looking for a way to determine if a user is using a mobile browser. We need to do that in PHP, by parsing the user agent string. I know this method has got many caveats, but we really need to do it that way.
Do you have any suggestion? A good (even if not perfect) updated code?
I know about WURFL, and I believe it's great, but it's not free to use anymore for non open source projects. By googling a bit, I also found this code: http://mobiforge.com/developing/story/lightweight-device-detection-php (and some variations), but I'm not sure about it. Looks like it's written really bad (look, for example, when they use $mobile_browser = '0' with the quotes around an integer...).
Can you recommend something?
Thank you,
Alessandro
