php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;
- }

-
- echo getbrowse();

- echo getbrowse() ;
