constructor of extended class not called

[delpino]

class cart extends abc {

function cart()  {
echo("hello 1");
} 

}

class abc {

function abc() {	
echo("hello 2");	
}

}

$cart_instance = new cart();

why doesn't this output "hello 2"? is the constructor of an extended not called? is there a workaround?

Well, the documentation says "Caution: For derived classes, the constructor of the parent class is not automatically called when the derived class's constructor is called."

Try calling it explicitly.
