?!?!? Non ho capito scusa

Cmq penso che la soluzione sia questa,


        Abstract Classes

An abstract class is a class that is only partially implemented by the 
programmer. It may contain one or more abstract methods. An abstract 
method is simply a function definition that serves to tell the 
programmer that the method must be implemented in a child class.

To create an abstract class we use the code shown in Listing 1:

*Listing 1: An Abstract PHP class*

<?php  
abstract class Weapon  
{  
    private $SerialNumber;  
    abstract public function fire();  


    public function __construct($SerialNumber)  
    {  
        $this->SerialNumber = $SerialNumber;  
    } 



    public function getSerialNumber()  
    {  
        return $this->SerialNumber;  
    }  
}  
?> 

Condividi ??
