How can PHP developers effectively separate program logic from content in a multilingual website?

To effectively separate program logic from content in a multilingual website, PHP developers can use language files to store all text content in different languages. By loading the appropriate language file based on the user's language preference, developers can easily switch between languages without mixing content and logic in the code. 

// Example of loading language files based on user's language preference
$user_language = $_GET['lang']; // Get user's language preference from URL parameter or session

if ($user_language == 'en') {
    include('lang/en.php'); // Load English language file
} elseif ($user_language == 'fr') {
    include('lang/fr.php'); // Load French language file
}

// Use language variables in the content
echo $lang['welcome_message'];
