It's good to mention that if user browser will not send HTTP_ACCEPT_LANGUAGE, the output from:

Locale::acceptFromHttp($_SERVER['HTTP_ACCEPT_LANGUAGE']);

Will be null.

So remember to set up a fail over scenario!

If you're struggling to figure out how to use this function in a project that only supports certain languages, move along.

Unfortunately, this function doesn't let you specify languages supported by your project - and since the internal header parsing and negotiation logic isn't exposed in any other way, you'll most likely want to ditch this function and go for a custom implementation of the same thing:

Didn't see this being documented anywhere and the bug hasn't been addressed yet, so to save headache for otherS, this method does a little weird thing with these different locales:

php > echo locale_accept_from_http("zh_TW");
zh
php > echo locale_accept_from_http("zh_CN");
zh

A nice way to detect humans. Bots usually dont have this HTTP_ACCEPT_LANGUAGE set.

Please note that this method can throw IntlException in some cases when the passed header string is invalid AND you have enabled exceptions. For example:

<?php

ini_set
('intl.use_exceptions', 1);

$header = 'fr-FR,fr;q=0.9,fr;q=0.9;q=0.8,en-gb;q=0.8;q=0.7,en;q=0.6,en;q=0.7;q=0.5,*;q=0.5;q=0.4';
var_dump(locale_accept_from_http($header));

?>

Returns:

PHP Warning: Uncaught IntlException: locale_accept_from_http: failed to find acceptable locale in ...
