This is a "feature", not a bug. I can see good uses for this, my
DataObject class uses this feature for dynamically adding instance
variables from database records.

If you run the following script and check the output, you will see the
that variable JUNK has been dynamically defined in the class X_Row() by
using the statement:

  $user->query_row->JUNK = "stuff";

This behaviour certainly wasn't what I would expect.

---
query_row = new X_Row();
  return;
 }
  }
  
  class X_Row
  { 
   var $USERNAME;
   var $PASSWORD;
   var $CHECKING;
   
  function X_Row() {
$this->USERNAME = NULL;
$this->PASSWORD = NULL;
$this->CHECKING = NULL;
   return;
   
   } //end function X_Row

 } //X_Row 
 

  $user = new X();
  //$user->query_row is of class X_Row
  
  //Therefore, the next statement should be valid, 
  //USERNAME has been declared in X_Row
  $user->query_row->USERNAME = 'mtl';
  
  //But the next statement shouldn't be
  //because the variable JUNK has not
  //been declared in the class
  $user->query_row->JUNK = 'stuff';
  
  $classname = get_class($user->query_row);
  $classvars = get_class_vars($classname);
  
  $query_row_class_vars = array_keys($classvars);
  
 
  echo "classname:{$classname}";
  echo "classvars:";
  var_dump($classvars);
  echo "query_row_class_vars";
  var_dump($query_row_class_vars);
  
  echo "HOW IS THIS POSSIBLE? SEE BELOW!";
  echo "user->query_row:";
  var_dump($user->query_row);

?>
