PHP: How to call function of a child class from parent class

inheritance, php

Solution

That's what abstract classes are for. An abstract class basically says: Whoever is inheriting from me, must have this function (or these functions).

abstract class whale
{

  function __construct()
  {
    // some code here
  }

  function myfunc()
  {
    $this->test();
  }

  abstract function test();
}


class fish extends whale
{
  function __construct()
  {
    parent::__construct();
  }

  function test()
  {
    echo "So you managed to call me !!";
  }

}


$fish = new fish();
$fish->test();
$fish->myfunc();

Problem

How do i call a function of a child class from parent class? Consider this: ``` class whale { function __construct() { // some code here } function myfunc() { // how do i call the "test" function of fish class here?? } } class fish extends whale { function __construct() { parent::construct(); } function test() { echo "So you managed to call me !!"; } } ```
