How can the use of __DIR__ and server-specific configurations improve the efficiency of website development in PHP?

Using __DIR__ in PHP allows for the creation of server-independent file paths, making it easier to move code between different environments without having to manually update file paths. Additionally, server-specific configurations can streamline the development process by allowing developers to easily switch between different server setups without having to rewrite code. 

// Using __DIR__ to create server-independent file paths
include __DIR__ . '/config/database.php';

// Server-specific configurations
if($_SERVER['SERVER_NAME'] === 'localhost'){
    // Local server configuration
    $db_host = 'localhost';
    $db_user = 'root';
    $db_pass = '';
} else {
    // Production server configuration
    $db_host = 'production_host';
    $db_user = 'production_user';
    $db_pass = 'production_pass';
}
