Question

PHP子类的同名函数必须与父类的参数一致吗？

class Model
{
public function add(array $data, array $table = [], $class = '', $function = '')
{
return $data['name'];
}
}

class User extends Model
{
protected $table = [];

public function add(array $data)
{
return parent::add($data, $this->table, __CLASS__, __FUNCTION__);
}
}

$class = new User();

echo $class->add(['name' => '张三'])

这样就出错了，必须把子类方法也定义成
public function add(array $data, array $table = [], $class = '', $function = '')
跟父类一样的参数才行，不想在子类也定义那么多冗余参数有方法吗，？
