如何访问关系数据库PHP中的属性(Yii 1.1)

'db' => array(
    'connectionString' => 'mysql:host=localhost;dbname=testdb',
    'emulatePrepare' => true,
    'username' => 'root',
    'password' => 'password',
    'charset' => 'utf8',
),

class User extends CActiveRecord {
    // ...
}

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

    // Getter/Setter方法
    public function getId() {
        return $this->id;
    }

    public function setId($value) {
        $this->id = $value;
    }

    public function getName() {
        return $this->name;
    }

    public function setName($value) {
        $this->name = $value;
    }

    public function getEmail() {
        return $this->email;
    }

    public function setEmail($value) {
        $this->email = $value;
    }
}

$user = new User;
$user->id = 1;
$user->name = 'John Doe';
$user->email = 'john@example.com';

echo $user->getId();   // 输出：1
echo $user->getName(); // 输出："John Doe"
echo $user->getEmail();// 输出："john@example.com"
