If you enable notices you will see that PHP outputs this : Notice:
ArrayIterator::next(): Array was modified outside object and internal
position is no longer valid.This line seems to be the problem //Test
if next stream is an option for ( $iterator->next();
$iterator->valid(); $iterator->next() ) { . I think that maybe the
problem is that you are accessing the array in the second for, PHP
detects that when it gets to the first for and it doesn't know if the
array is still the same and starts over . Anyway, you are trying to
iterate over the array in a pretty strange way :) . My advice is to
use $arrayobject->count() to see how many elements you have and then
iterate with a for($i=0; $i < $arrayobject->count(); $i++) . Also, if
you accept only some options than just use getopt function.

for loop is not good choice. while loop is more reasonable. this is the
part of the code i use in production
$collection = new ArrayObject();
/* Sorty Keys */
$collection->sortByKeys();
/* fetch iterator */
$iterator = $collection->getIterator();
while ($iterator->valid()) {
/* fetch current */
$current = $iterator->current();
/* put code here */
/* get next */
$iterator->next();
}
