主要是为了防止对方修改User-Agent

主要是为了防止对方修改User-Agent

php所有的关于客户端的信息，都是通过客户端HTTP的Header中得到的，因此它只能是一个参考信息，大多数情况下只能用来做统计数据。你也不必太过担心用户修改user-agent，毕竟这只是少数用户。

你不能依靠这些无法控制的数据做一些可靠性要求较高的事情，说白了，这个东西就是个君子协议，大多数情况下，大家都愿意做君子。

感觉这个意义不大吧，浏览器能做的，程序都能做，想摸你就摸你:-P

我觉得你遇到的问题可能跟这个哥们用360取不到正确UA一样。
参考这个问题 http://segmentfault.com/q/10100000001...

不能。

HTTP协议中的UserAgent头信息是可以随意伪造的，是不可靠的。

可以用它来做大量收集和分析
