How does the use of static methods in PHP CRUD systems impact development and maintenance?

Using static methods in PHP CRUD systems can make the code tightly coupled and harder to test, as static methods cannot be easily mocked or stubbed. This can lead to difficulties in maintaining and extending the codebase. To address this issue, it is recommended to use dependency injection and instance methods instead of static methods. 

class User {
    private $db;

    public function __construct(Database $db) {
        $this->db = $db;
    }

    public function create($data) {
        // Insert user data into the database
    }

    public function update($id, $data) {
        // Update user data in the database
    }

    public function delete($id) {
        // Delete user data from the database
    }

    public function getById($id) {
        // Retrieve user data from the database
    }
}

$db = new Database();
$user = new User($db);

$user->create($userData);
$user->update($userId, $newData);
$user->delete($userId);
$userData = $user->getById($userId);
