Dan, one final happy footnote:

I was successfully able to convert my ActionHandler class into PHP4's 
closest thing to a Singleton Design Pattern:

class ActionHandler {

  // UNCOMMENT THIS LINE IN PHP 5
  // static $instance =& new ActionHandler();

  function &ActionHandler() {}

  function &getActionHandler() {
   static $instance;
   if (!isset($instance)) $instance =& new ActionHandler();
   return $instance;
  }

  function &getErrorArray() {
   return ActionHandler::setErrorArray();
  }

  function &setErrorArray($additionalErrorArray) {
   static $errorArray;
   if (is_array($additionalErrorArray)) $errorArray += 
$additionalErrorArray;
   return $errorArray;    // THROWS ARRAY BUT IS CAUGHT BY getErrorArray()
  }

}

And then in my main script, index.php, I simply do this:

$ah =& ActionHandler::getActionHandler();
// BLAH BLAH BLAH
$ah = null;

And then with all of my classes I use the "static" type class notations 
to use the class:

if (somethingBreaks) ActionHandler::setErrorArray(array('action' => 
'Oops you goofed'));

Tested it out and everything works perfectly!  Thanx for your help
