Hi Dary! I don't understand the point. If I comment out the "abstract protected function showProject($project);" line in class Manager, the results are same (with and without given parameter), I get back the project name of instance I've got to the method.

$emp1 = new Employee();
echo $emp1->showProject() // The result is: "I'm working in 'Apple' project."

$emp2 = new Employee();
echo $emp2->showProject("Banana"); // The result is: "I'm working in 'Banana' project."

Nice tutorial. However, you mentioned some topics that you have taught that are supposed to be on this playlist but are not there. For example you mentioned having taught PHP Interface but it's not on this playlist. Do you have another playlist?

Are abstract classes similar to interface classes in Java and Kotlin?

What's the point of writing the following code if it's never used?

public function startProject($project)
{
return
}

In welke gevallen zou je een abstract class gebruiken? Het voelt nu als extra code zonder dat het echt nut heeft.
