PHPDoc扩展类的不同返回类型

Question

I have created my own DB - Model structure which is similar to Laravel. I have been facing with 2 problems.

I have a Model class which all of my models extend it. For example, my User class extends Model. I want to return that get() method return type of class which is extended.

Is this possible?

Class Model extends DB {
    /**
     * @return AnyClassThatExtended
     */
    function get()
    {
    }
}

Class User extends Model {
    function test() {
        $user->get(); // I want it to return User type of object
    }
}

Answer 1

You should use

private static $instance;

/**
 * return static
 */
public function get() {
    if (is_null(self::$instance)) {
        self::$instance = new static();
    }

    return self::$instance;
}

because you are returning current class that you are at (if I understand correctly)

It's possible that PHPStorm does not recognize it
