javascript - php HTTP_USER_AGENT 变量帮助检测浏览器

Question

我想编写一个网页，以便根据浏览器显示不同的页面

我认为 SERVER [HTTP_USER_AGENT] 将是一个有用的变量，但是

但是在 Chrome 下查看页面会出现这个

Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 
(KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36 

查看 MSIE 11 下的页面会给我这个

Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; ASU2JS; rv:11.0) like Gecko 

火狐-

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0 

海猴-

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0 
SeaMonkey/2.26.1 

我该如何解决这个问题？我想设计我的网站，以便可以显示两个不同的页面

MSIE 10 或更早版本，

或

(MSIE11 + Chrome + FireFox)

谢谢堆栈溢出!
