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

I've got this one, which sets a cookie. And as you can see, it first checks if the language is posted by the user. Because browser language not always tells about the user.

<?php   
    $lang = getenv("HTTP_ACCEPT_LANGUAGE");
    $set_lang = explode(',', $lang);
    if (isset($_POST['lang'])) 
        {
            $taal = $_POST['lang'];
            setcookie("lang", $taal);
            header('Location: /p/');
        }
    else 
        {
            setcookie("lang", $set_lang[0]);
            echo $set_lang[0];
            echo '<br>';
            echo $set_lang[1];
            header('Location: /p/');
        } 
?>
