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;

                }//开源代码phpfensi.com

                return $browseinfo;

        }

//应用方法

//在ie中

echo getbrowse(); //internet explorer 6.0

//在firefox中

echo getbrowse() ;//netscape navigator 5.0
