PHP如何判断浏览器类型

因为浏览器在和服务器连接时候都会先发送一些包含自己信息的内容(浏览器类型、语言)。
这里我们主要分析的是_SERVER["HTTP_USER_AGENT"](浏览器类型)
我们所要做的就是把这些内容读出来,然后用strpos或者preg_match函数来对比就可以了。

<?php
 2  if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0″)) 
 3   echo "Internet Explorer 8.0″; 
 4  else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0″)) 
 5   echo "Internet Explorer 7.0″; 
 6  else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0″)) 
 7   echo "Internet Explorer 6.0″;
 8  else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3″))
 9   echo "Firefox 3″;
10  else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2″))
11   echo "Firefox 2″;
12  else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))
13   echo "Google Chrome";
14  else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))
15   echo "Safari";
16  else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))
17   echo "Opera";
18  else echo $_SERVER["HTTP_USER_AGENT"]; 
19  ?>
