Get operating system language in PHP

We can detect requesting browser’s language using PHP’s super global variable $_SERVER. It is a superglobal variable which holds information about headers, paths, and script locations. It is basically an associative array in PHP which has keys like SERVER_NAME, SERVER_ADDR, REQUEST_METHOD, etc.

We can use HTTP_ACCEPT_LANGUAGE key to get the language of the browser.



Example 1


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




If your website has different pages for different languages, you can use this method in order to redirect to the page according to the user’s browser’s language.

Example 2


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

// Redirect browser
header("Location:" . $lang . "/index.php");
