我有一个实现几个抽象方法的类.当我扩展该类时,我得到以下致命错误消息：
Class CI_Controller_Rest contains 6 abstract methods and must therefore be declared abstract or implement the remaining methods
抽象方法的类：
class CI_Controller_Rest extends CI_Controller {
public function __construct() {
parent::__construct();
}
abstract public function index();
abstract public function get();
abstract public function head();
abstract public function post();
abstract public function put();
abstract public function delete();
}
我扩展CI_Controller_Rest的类：
class Welcome extends CI_Controller_Rest {
public function __construct()
{
parent::__construct();
}
public function index() {}
public function get() {}
public function head() {}
public function post() {}
public function put() {}
public function delete() {}
}
我该怎么办？
如果一个类有一个或多个抽象函数,那么
it MUST be declared as an abstract class：
abstract class CI_Controller_Rest extends CI_Controller {
public function __construct() {
parent::__construct();
}
abstract public function index();
abstract public function get();
abstract public function head();
abstract public function post();
abstract public function put();
abstract public function delete();
}
