PHP如何实现子类的属性全部都有 toArray()方法？
调用之后 ,变成了数组
父类如何设计呢？？
闭关修行中......
interface Arrayable { public function toArray(); } class parent implents Arrayable { public function toArray() { // to do }; } class children extends parent{ }
Just write a toarray method for the parent class, that’s it,
Write an interface implementation, or use the parent class for inheritance
