Challenge Task 3 of 4
In the Penguin.php file, create a "Penguin" class that inherits from the Bird Class. Make sure you define the abstract method of the Bird Class.
<?php
// abstract bird class
abstract class Bird
{
public $color,$wingspan,$habitat;
public function eat()
{
}
public function sleep(){
}
public abstract function communicate($type);
}
<?php
// real Mockingbird class (
<?php
// real penguin class (cannot fly)
abstract class Penguin interface Bird
{
abstract public function eat();
}

You are doing it wrong, the penguin class shouldn't be abstract, interface a wrong keyword it needs to be extend and the method is wrong you need to make the communicate method with a body:
<?php
class Penguin extends Bird {
public function communicate($type) {
}
}
