PHP简单判断当前使用的是什么浏览器

php简单判断当前使用的是什么浏览器，判断浏览器类型的方法，方便统计网站访问用户使用浏览器的比例。

判断浏览器类型方法

 1 function userbrowser() { 
 2     $user_osagent = $_server['http_user_agent']; 
 3  
 4     if (strpos($user_osagent, "maxthon") && strpos($user_osagent, "msie")) { 
 5         $visitor_browser = "maxthon(microsoft ie)"; 
 6     } elseif (strpos($user_osagent, "maxthon 2.0")) { 
 7         $visitor_browser = "maxthon 2.0"; 
 8     } elseif (strpos($user_osagent, "maxthon")) { 
 9         $visitor_browser = "maxthon"; 
10     } elseif (strpos($user_osagent, "msie 9.0")) { 
11         $visitor_browser = "msie 9.0"; 
12     } elseif (strpos($user_osagent, "msie 8.0")) { 
13         $visitor_browser = "msie 8.0"; 
14     } elseif (strpos($user_osagent, "msie 7.0")) { 
15         $visitor_browser = "msie 7.0"; 
16     } elseif (strpos($user_osagent, "msie 6.0")) { 
17         $visitor_browser = "msie 6.0"; 
18     } elseif (strpos($user_osagent, "msie 5.5")) { 
19         $visitor_browser = "msie 5.5"; 
20     } elseif (strpos($user_osagent, "msie 5.0")) { 
21         $visitor_browser = "msie 5.0"; 
22     } elseif (strpos($user_osagent, "msie 4.01")) { 
23         $visitor_browser = "msie 4.01"; 
24     } elseif (strpos($user_osagent, "msie")) { 
25         $visitor_browser = "msie 较高版本"; 
26     } elseif (strpos($user_osagent, "netcaptor")) { 
27         $visitor_browser = "netcaptor"; 
28     } elseif (strpos($user_osagent, "netscape")) { 
29         $visitor_browser = "netscape"; 
30     } elseif (strpos($user_osagent, "chrome")) { 
31         $visitor_browser = "chrome"; 
32     } elseif (strpos($user_osagent, "lynx")) { 
33         $visitor_browser = "lynx"; 
34     } elseif (strpos($user_osagent, "opera")) { 
35         $visitor_browser = "opera"; 
36     } elseif (strpos($user_osagent, "konqueror")) { 
37         $visitor_browser = "konqueror"; 
38     } elseif (strpos($user_osagent, "mozilla/5.0")) { 
39         $visitor_browser = "mozilla"; 
40     } elseif (strpos($user_osagent, "firefox")) { 
41         $visitor_browser = "firefox"; 
42     } elseif (strpos($user_osagent, "u")) { 
43         $visitor_browser = "firefox"; 
44     } else { 
45         $visitor_browser = "其它"; 
46     } 
47     return $visitor_browser; 
48 }

直接调用 userbrowser()

<?php echo "您现在使用的浏览器是：" . userbrowser();?>
