在php中我们有个全局变量$_server['http_user_agent'];可以获取用户所有信息，我们要经过处理才可以判断用户浏览器是那种型的，下面的函数就可以准确的用户浏览器版本号代码。

function getbrowse()

                        }
                }

                        $part = $temp[0];
                        $temp = explode('/', $part);
                        $browserver = $temp[1];
                        $temp = explode(' ', $browserver);
                        $browserver = $temp[0];

                } else {
                        $browseinfo = false;
                }
                return $browseinfo;
        }
 //应用方法
 
 //在ie中
 echo getbrowse(); //internet explorer 6.0
 //在firefox中
 echo getbrowse() ;//netscape navigator 5.0
