PHP如何识别系统语言或浏览器语言
有两个站cn,en
需要当在国外访问cn的时候直接跳转到en去
请问有什么方法可以完成。
我用的

<br />
preg_match('/^([a-z\-]+)/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches);<br />
$lang = $matches[1];<br />
switch ($lang) {<br />
	case 'zh-cn' :<br />
		//header('Location: http://cn.test.com/');<br />
		echo "中国";<br />
		break;<br />
	case 'zh-tw' :<br />
		// header('Location: http://tw.test.com/');<br />
		echo "台湾";<br />
		break;<br />
	case 'ko' :<br />
		//header('Location: http://ko.test.com/');<br />
		break;<br />
	default:<br />
		// header('Location: http://en.test.com/');<br />
		echo "英文";<br />
		break;<br />
}<br />
Copy after login

火狐和IE显示的不同,IE是正常的。
如直接显示$_SERVER['HTTP_ACCEPT_LANGUAGE']
IE为:zh-cn
火狐为:zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3
