PHP static objects giving a fatal error?

Well, I think your Customer::getInstance() method is flawed. It should look like this: static function getInstance() { if(self::$class == false) { self::$class = new Customer; return self::$class; // ADDED! } else { return self::$class; } } In the if(self::$class == false) branch you are creating the instance of the class, but you don't return it You could also rewrite it as such: static function getInstance() { if(self::$class == false) { self::$class = new Customer; } return self::$class; } To make it a bit shorter.

DRY: Don't Repeat Yourself static function getInstance() { if(self::$class == false) { self::$class = new Customer; } return self::$class; } And for Sinlgetons it is also important to prevent __clone() from being used. Making it private should solve that problem: private function __clone() {}.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
