Bug description: LimitIterator with empty ArrayIterator
Description:
------------
iterating over an empty seekable iterator causes an unexpected exception.
with actual implementation of LimitIterator::rewind() there is no way to
do an empty loop over an empty ArrayIterator.
i suggest this implementation for LimitIterator::rewind() method
function rewind(){
$this->it->rewind();
$this->pos = 0;
if($this->it->valid()){ // check for empty iterators
$this->seek($this->offset);
}
}
Reproduce code:
---------------
$it = new ArrayIterator(array());
$limIt = new LimitIterator($it, 0, 5);
foreach ($limIt as $item){
echo $item;
}
Expected result:
----------------
an empty loop
Actual result:
--------------
Uncaught exception 'OutOfBoundsException' with message 'Seek position 0 is
out of range'
