Please note that if you are using IteratorIterator with a SplQueue then the valid() method of the
iterator will retun false even if there are elements to be iterated in the queue.
Example:
<?php
$q = new SplQueue();
$q->enqueue('something');
$it = new IteratorIterator($q);
print (int) $it->valid(); //outputs 0
// but if you call rewind() first then check for valid() it works:
$it->rewind();
print (int) $it->valid(); //outputs 1
?>
I don't know if this behavior is intended, but this is what I get on PHP 5.5.9-1ubuntu4.5
