Are there specific PHP functions or methods that can streamline language detection and variable assignment?

When working with multilingual websites or applications, it is important to detect the user's preferred language and assign it to a variable for further processing. PHP provides the `$_SERVER['HTTP_ACCEPT_LANGUAGE']` variable which contains the user's preferred language settings. By parsing this variable and extracting the language code, we can streamline the language detection and variable assignment process.

// Get the user's preferred language from the HTTP_ACCEPT_LANGUAGE header
$userLanguage = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

// Assign the detected language to a variable for further processing
$language = ($userLanguage == 'fr') ? 'French' : 'English'; // Example assigning language based on detected code

echo "Detected language: " . $language;
