Description:
------------
When passing another AppendIterator to AppendIterator::append(), the entire AppendIterator is returned during iteration instead of the individual entries.
Test script:
---------------
<?php
$array_a = new ArrayIterator(array('a', 'b', 'c'));
$array_b = new ArrayIterator(array('d', 'e', 'f'));
$iterator = new AppendIterator;
$iterator->append($array_a);
$iterator2 = new AppendIterator;
$iterator2->append($iterator);
$iterator2->append($array_b);
foreach ($iterator2 as $current) {
echo $current;
}
Expected result:
----------------
abcdef
Actual result:
--------------
PHP Catchable fatal error: Object of class ArrayIterator could not be converted to string

That's probably due to changes from #73471, however you're not quite following the contract: when iterating manually you need to call ->rewind() beforehand. foreach ($it as $key => $value) { ... } translates to $it->rewind(); while ($it->valid()) { $key = $it->key(); $value = $it->current(); ... $it->next(); } Adding the ->rewind() gives the correct behavior.
