note 89129 deleted from function.iterator-count by cmb

Note Submitter: donovan jimenez ---- Be careful of thinking of iterators and arrays as completely analogous in your PHP code. iterator_count will NOT return your iterator to its previous state after looping through it for the count. Any iterator implementation that also implements Countable::count isn't required to do so either. This is clearest in example form: <?php $array = array( 1 => 'foo', 2 => 'bar' ); foreach ($array as $key => $value) { echo "$key: $value (", count($array), ")\n"; } $iterator = new ArrayIterator($array); foreach ($iterator as $key => $value) { echo "$key: $value (", iterator_count($iterator), ")\n"; } ?> outputs: 1: foo (2) 2: bar (2) 1: foo (2) Notice that because of how iterator_count works we never see the second iterator value because the next call to then Iterator::valid() implementation returns false (its at the end of the iterator).
