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 !!";
  }

}

```
