本文实例讲述了php获取用户浏览器版本的方法。分享给大家供大家参考。具体分析如下:

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哪种类型的,下面的函数就可以准确的用户浏览器版本号代码.

代码如下:

function getbrowse()
{
 $agent = $_server['http_user_agent'];
 $browser = '';
 $browserver = '';
 $browser = array('lynx', 'mosaic', 'aol', 'opera', 'java', 'macweb', 'webexplorer', 'omniweb');
 for($i = 0; $i   if(strpos($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

希望本文所述对大家的php程序设计有所帮助。
