Detect Browser Language in PHP

Question

I use the following PHP script as index for my website.

This script should include a specific page depending on the browser\'s language (automatically detected).

Answer 1

The official way to handle this is using the PECL HTTP library. Unlike some answers here, this correctly handles the language priorities (q-values), partial language matches and will return the closest match, or when there are no matches it falls back to the first language in your array.

PECL HTTP:
http://pecl.php.net/package/pecl_http

How to use:
http://php.net/manual/fa/function.http-negotiate-language.php

$supportedLanguages = [
    'en-US', // first one is the default/fallback
    'fr',
    'fr-FR',
    'de',
    'de-DE',
    'de-AT',
    'de-CH',
];

// Returns the negotiated language 
// or the default language (i.e. first array entry) if none match.
$language = http_negotiate_language($supportedLanguages, $result);
