chaining methods what needs to be changed in class
I have the following class and I want to implement chaining methods. I am kinda teaching my ownself so I thought it would be neat to test chaining. However that didnt work. What would I need to do that

    echo $animal->name.'  says'.$animal->speak()->likes()."<br />";	


here is my complete code 

    <?php 
    class Animal{
    	
    	var $name;
    	function __construct(){
    		
    		$this->name = $name;
    		
    	}
    	
    }
    
    
    class Dog extends Animal{
    	
    	
    	public function speak(){
    		
    		return "Woof Woof";
    		
    		
    	}
    	public function likes(){
    		
    		return "steaks";
    		
    		
    	}
    	
    }
    
    class Cat extends Animal{
    	
    	public function speak(){
    		
    		return "Meow Meow";
    		
    	}
    	
    	public function likes(){
    		
    		return "tuna";
    		
    	}
    	
    }
    
    $animals = array(new Dog('skippy'), new Cat('snowball'));
    foreach($animals as  $animal){
    	echo $animal->name.'  says'.$animal->speak()->likes()."<br />";	
    
    
    }
    ?>
