从子类调用函数

Question

Given I have an abstract class:

abstract class User{

  private function getNumber(){

      return 'Get number';
  }
}

With the child class

class UserComments extends User{


   public function rows(){
    return $this->getNumberOfRows();
 }
}

Question:

Is there any way to call the getNumber function when I try to call getNumberOfRows method in child class, or when I call getNumberOfRows() in child class I want getNumber to be called instead ?

Answer 1

Due to PHP's Object inheritance you can directly call the specific method. However, in your example the getNumberOfRows() function is missing.

class UserComments extends User {

   public function rows() {
      return $this->getNumber();
   }
}
