利用PHP代码实现网页自动判断转向
用户可接受的语言信息,放在$_SERVER['HTTP_ACCEPT_LANGUAGE']里,变量信息是类似这样的 "zh-cn", 假如是多语言列,是类似 "zh-cn,en;q=0.8,ko;q=0.5,zh-tw;q=0.3"
下面的问题可以迎刃而解了。
代码:
error_reporting(E_ALL ^ E_NOTICE);
// 分析 HTTP_ACCEPT_LANGUAGE 的属性
// 这里只取第一语言设置 (其他可根据需要增强功能,这里只做简单的方法演示)
preg_match('/^([a-z-] )/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches);
$lang = $matches[1];
switch ($lang) {
case 'zh-cn' :
header('Location: http://cn.example.com/');
break;
case 'zh-tw' :
header('Location: http://tw.example.com/');
break;
case 'ko' :
header('Location: http://ko.example.com/');
break;
default:
header('Location: http://en.example.com/');
break;
}
