What are the best practices for accessing and using language files in PHP scripts to display text in different languages?

To display text in different languages in PHP scripts, it's best practice to use language files that contain translations for each language. By accessing these language files based on the user's language preference, you can easily display text in the appropriate language without cluttering your code with multiple language strings. 

// Assuming language files are stored in a directory named 'languages'
// and each file contains translations in an associative array

// Get user's preferred language (e.g., from session or cookie)
$user_language = 'en'; // Assuming English as default

// Load language file based on user's preference
$language_file = 'languages/' . $user_language . '.php';

if (file_exists($language_file)) {
    include $language_file;
} else {
    // Fallback to default language file
    include 'languages/en.php';
}

// Access translated text using the language array
echo $lang['hello']; // Output: Hello
