What are the benefits of using a DIC in PHP development?

When developing PHP applications, managing dependencies manually can become cumbersome and error-prone. Using a Dependency Injection Container (DIC) can help streamline the process by centralizing the management of object creation and dependency injection. This can lead to more maintainable and testable code, as well as improved flexibility and scalability. 

// Example of using a DIC in PHP development

// Create a DIC instance
$dic = new DIC();

// Register dependencies
$dic->register('db', function() {
    return new DatabaseConnection('localhost', 'username', 'password', 'database');
});

$dic->register('user_repository', function() use ($dic) {
    return new UserRepository($dic->get('db'));
});

// Resolve dependencies
$userRepository = $dic->get('user_repository');
$user = $userRepository->getUserById(1);
