How can PHP developers ensure that language-specific content is displayed correctly when switching languages on a website?

When switching languages on a website, PHP developers can ensure that language-specific content is displayed correctly by using language files or arrays to store translations for each language. By dynamically loading the appropriate language file based on the user's language preference, developers can easily display the correct content in the selected language. 

// Define language files for each supported language
$languageFiles = [
    'en' => 'english.php',
    'es' => 'spanish.php',
    'fr' => 'french.php',
];

// Load the appropriate language file based on user's language preference
$userLanguage = $_GET['lang'] ?? 'en'; // Default to English if no language preference is set
$languageFile = $languageFiles[$userLanguage];
require_once($languageFile);

// Access language-specific content using translations defined in the language file
echo $translations['welcome_message'];
