note 119249 added to arrayiterator.seek

<?php //seek alter the iterator's internal indice instead of the value that key() returns. //This is a big trap if combining with uasort/natsort function. $a = new ArrayObject([4,3,2,1]); $it = $a->getIterator(); $it->natsort(); //The Iterator preserve the key while sorting the array $it->rewind(); $first = $it->key(); //The first element is 1 and it's key is 3 echo $first.
