New Comment:
Thats fine, and that works.
I guess this needs to be documented inside of setIteratorMode(), I
would have never guessed that flags are replaced, my initial assumption
would be that they are OR'd with the existing flags.
Thanks for clearing this up.

The reason is that setIteratorMode replaces the iterator flags
entirely, so you need to specify the order of iteration as well if you
want to change the KEEP/DELETE.
Since you use a stack, simply use:
SplDoublyLinkedList:: IT_MODE_DELETE |
SplDoublyLinkedList::IT_MODE_LIFO

Description:
------------
Attempting to change the IteratorMode throws an exception.
The is probably due to the code that changes the LIFO/FIFO ordering
that is also settable via the inherited method of
SplDoublyLinkedList::setIteratorMode().
Reproduce code:
---------------
<?php
$s = new SPLStack();
$s->setIteratorMode(SplDoublyLinkedList::IT_MODE_DELETE);
Expected result:
----------------
Do not throw exception on the following use cases:
->setIteratorMode(SplDoublyLinkedList::IT_MODE_DELETE)
->setIteratorMode(SplDoublyLinkedList::IT_MODE_KEEP)
Actual result:
--------------
PHP Fatal error: Uncaught exception 'RuntimeException' with message
'Iterators' LIFO/FIFO modes for SplStack/SplQueue objects are frozen' in
path/to/test-splstack.php:4
Stack trace:
#0 path/to/test-splstack.php(4):
SplDoublyLinkedList->setIteratorMode(1)
#1 {main}
thrown in path/to/test-splstack.php on line 4
