question about array() and unset()

If I have an array like:

$_SESSION['items']= array('item1', 'item2', 'item3')

and I do:
unset($_SESSION['items'][1]) in order to remove 'item2'

Do the remaining values get re-indexed like:
$_SESSION['items'][0] = 'item1'
$_SESSION['items'][1] = 'item3'

If not, how do I achieve the above re-indexing?

Also, if the values are not re-indexed will count($_SESSION['items']) still equal 3?

1. Values not re-indexed. You must do the following to reindex values:

$_SESSION['items']= array('item1', 'item2', 'item3');
unset($_SESSION['items'][1]);
sort($_SESSION['items']);

2. count($_SESSION['items']) === 2.
