To your class add:
public function __get($name) { return NULL; } public function __set($name, $value) { }
Explanation: those two methods will intercept any access to a non-existant and/or protected/private property, also preventing its creation if it does not exists.

As per @DCoder suggestion, you could also do:
public function __get($name) { throw new Exception("Property $name cannot be read"); } public function __set($name, $value) { throw new Exception("Property $name cannot be set"); }
