Understanding the Data Mapper Pattern

Ini adalah sebuah pola yang sangat penting yang harus kita lakukan.

Benefits of Using the Data Mapper Pattern

  • S01; FLT: 0 AF3; Decouplaing: 501; FLT: 1 123; ASA3; Deparates s investigator logic data pereskusi akses.
  • 1f 1f; FILT; 0 = 0 = 3. Testability: 1f 1; FLT: 1 123; 513; Business logic can be tested indedeny of the dadatase.
  • Pertama, FLT: 0; Flexibility; Flexbility:
  • Pertama; FLT: 0; 3; Mainstability: 501; FLT: 1 123; OLE3; Clear separation of concerns simple fies code manajement.

Implementing the Data Mapper is PHP

Implementing the Data Mappar pola tidak sengaja creatines creatreg three main components:

  • FLT: 0 = 33. Objects Domais: FIL1; FLT: 1 = 3; Represent the experiests entities.
  • Pertama; FLT: 0 ASA3; Ade3; Data Mapper Classes:
  • Pertama, FLT: 0 ASA3; Databasee Layer:

Periksa: User Entity

Supposie we have a User class representting a usar is oar appecation:

class User {
 public $id;
 public $name;
 public $email;

 public function __construct($id = null, $name = '', $email = '') {
 $this->id = $id;
 $this->name = $name;
 $this->email = $email;
 }
}

CreakingtheDateMapper Crass

The Data Mapper for to e User class manajer data interactions:

class UserMapper {
 protected $pdo;

 public function __construct(PDO $pdo) {
 $this->pdo = $pdo;
 }

 public function findById($id) {
 $stmt = $this->pdo->prepare('SELECT * FROM users WHERE id = :id');
 $stmt->execute([':id' => $id]);
 $row = $stmt->fetch();

 if ($row) {
 return new User($row['id'], $row['name'], $row['email']);
 }
 return null;
 }

 public function save(User $user) {
 if ($user->id) {
 $stmt = $this->pdo->prepare('UPDATE users SET name = :name, email = :email WHERE id = :id');
 $stmt->execute([
 ':name' => $user->name,
 ':email' => $user->email,
 ':id' => $user->id
 ]);
 } else {
 $stmt = $this->pdo->prepare('INSERT INTO users (name, email) VALUES (:name, :email)');
 $stmt->execute([
 ':name' => $user->name,
 ':email' => $user->email
 ]);
 $user->id = $this->pdo->lastInsertId();
 }
 }
}
