How to recognize user language in PHP

Question

有没有办法解析HTTP_USER_AGENT以获取当前的用户语言？

Answer 1

Try:

$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
echo $lang;

Answer 2

You may want to try HTTP_ACCEPT_LANGUAGE in the $_SERVER superglobal.

Take a look at http://php.net/manual/en/reserved.variables.server.php for more information.

This will return a value like 'en-us' which you can then break down as needed.

Answer 3

从理论上讲，你可以尝试在用户代理周围做一些体操，但是还有一个似乎可以解决问题的Accept-Language标题！

Answer 4

Another common way (as to create an alternative) to do this is to check the user's IP against a database of IP's with associated regions. The most common database for this is GeoIP ( http://www.maxmind.com ). It's worth taking a look at if you're interested. You can then proceed in changing the language to that of the region.
