php教程 获取用户浏览器版本代码
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()
        {
                $agent = $_server[http_user_agent];
                $browser = ;
                $browserver = ;
                $browser = array(lynx, mosaic, aol, opera, java, macweb, webexplorer, omniweb);
                for($i = 0; $i <= 7; $i ++){
                        if(strpos($agent, $browsers[$i])){
                                $browser = $browsers[$i];
                                $browserver = ;
                        }
                }
                if(ereg(mozilla, $agent) && !ereg(msie, $agent)){
                        $temp = explode((, $agent);
                        $part = $temp[0];
                        $temp = explode(/, $part);
                        $browserver = $temp[1];
                        $temp = explode( , $browserver);
                        $browserver = $temp[0];
                        $browserver = preg_replace(/([d.]+)/, 1, $browserver);
                        $browserver = $browserver;
                        $browser = netscape navigator;
                }
                if(ereg(mozilla, $agent) && ereg(opera, $agent)) {
                        $temp = explode((, $agent);
                        $part = $temp[1];
                        $temp = explode(), $part);
                        $browserver = $temp[1];
                        $temp = explode( , $browserver);
                        $browserver = $temp[2];
                        $browserver = preg_replace(/([d.]+)/, 1, $browserver);
                        $browserver = $browserver;
                        $browser = opera;
                }
                if(ereg(mozilla, $agent) && ereg(msie, $agent)){
                        $temp = explode((, $agent);
                        $part = $temp[1];
                        $temp = explode(;, $part);
                        $part = $temp[1];
                        $temp = explode( , $part);
                        $browserver = $temp[2];
                        $browserver = preg_replace(/([d.]+)/,1,$browserver);
                        $browserver = $browserver;
                        $browser = internet explorer;
                }
                if($browser != ){
                        $browseinfo = $browser. .$browserver;
                } 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
