for ZE1 this is definetly a (documented?) feature ...
i don't know about ZE2, but for backwards compatibility reasons i think
this 'feature' will stay ...
any authoritative comments on this?

Can someone from an authority standpoint look into this?
If it is a feature, then it is potentially quite dangerous,
both from a security standpoint as well as from on
operational standpoint.
Why bother having class variables at all if that is the
case?

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.
-----------------------
<?php
class X {
var $query_row;
function X() {
$this->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:{$classname}<br>";
echo "classvars:<br>";
var_dump($classvars);
echo "<br>query_row_class_vars<br>";
var_dump($query_row_class_vars);
echo "<br><br>HOW IS THIS POSSIBLE? SEE BELOW!!!!!!!!!";
echo "<br>user->query_row:<br>";
var_dump($user->query_row);
?>
