有一个全新的解决方案使用Zend框架。从Zend_HTTP_UserAgent的链接开始:

在检测移动浏览器上有开源脚本,可以在Apache、ASP、ColdFusion、JavaScript和PHP中实现这一点。

Just a thought but what if you worked this problem from the opposite direction? Rather than determining which browsers are mobile why not determine which browsers are not? Then code your site to default to the mobile version and redirect to the standard version. There are two basic possibilities when looking at a mobile browser. Either it has javascript support or it doesn't. So if the browser does not have javascript support it will default to the mobile version. If it does have JavaScript support, check the screen size. Anything below a certain size will likely also be a mobile browser. Anything larger will get redirected to your standard layout. Then all you need to do is determine if the user with JavaScript disabled is mobile or not. According to the W3C the number of users with JavaScript disabled was about 5% and of those users most have turned it off which implies that they actually know what they are doing with a browser. Are they a large part of your audience? If not then don't worry about them. If so, whats the worst case scenario? You have those users browsing the mobile version of your site, and that's a good thing.

我最喜欢的移动浏览器检测机制是WURFL。它经常更新,适用于每一个主要的编程/语言平台。
