(PHP 5 >= 5.3.0, PHP 7)

SplStack::setIteratorModeSets the mode of iteration


void SplStack::setIteratorMode ( int $mode )



There is only one iteration parameter you can modify.

  • The behavior of the iterator (either one or the other):
    • SplDoublyLinkedList::IT_MODE_DELETE (Elements are deleted by the iterator)
    • SplDoublyLinkedList::IT_MODE_KEEP (Elements are traversed by the iterator)

The default mode is 0x2 : SplDoublyLinkedList::IT_MODE_LIFO | SplDoublyLinkedList::IT_MODE_KEEP


The direction of iteration can no longer be changed for SplStacks. Trying to do so will result in a RuntimeException being thrown.
