Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This is expected behaviour due to the way that iterators work with
foreach. When
$j is 4, the iterator gets rewound. At this point $j is still 4 which is
then
echoed. Then when going on to the next iteration (where you expect to
get $j = 1)
the $i->next() method is called, moving to the second item.

Description:
------------
ArrayIterator::rewind() doesn't rewind to first element, but to second.
Test script:
---------------
<?php
$i = new ArrayIterator(array(1,2,3,4,5,6));
$r = false; # To prevent looping infinitely.
foreach($i as $j) {
if ($j == 4 && $r == false) {
$i->rewind();
$r = true;
}
echo $j.",";
}
Expected result:
----------------
1,2,3,4,1,2,3,4,5,6,
Actual result:
--------------
1,2,3,4,2,3,4,5,6,
