What are the potential pitfalls of directly embedding language strings in PHP code instead of using language files?

Embedding language strings directly in PHP code can make it difficult to maintain and update translations, as every change would require editing the code itself. This approach also makes it challenging to collaborate with translators who may not be familiar with PHP. Using language files allows for easier management of translations and separation of concerns, making the code more maintainable and scalable. 

// Bad practice: Embedding language strings directly in PHP code
echo "Hello, World!";

// Good practice: Using language files for translations
$language = 'en';
$translations = include('translations/' . $language . '.php');
echo $translations['hello_world'];
