When you get the book (or sooner if you look online), you should  
check out the Singleton pattern.

If your class method can't be static (because it needs access to  
$this - which isn't available for static methods), then a Singleton  
is a good option to use if you only  need one instance of the object  
in your app.

It works basically like this:

class Error
{
   private static $_instance = null;

   public static function singleton()
   {
     if (self::$_instance === null) {
       self::$_instance = new Error();
     }

     return self::$_instance;
   }
}

Then, wherever you need to get your Error object, just call

$error = Error::singleton();
