Answer 1

You should use json_encode like following:

json_encode(array('deleted' => $deleted, 'undeleted' => $undeleted));

And you have to get vars with data.undeleted and data.deleted

$.post('delete.php', {'deletearray':deletearray, 'dir':dir}, function(data) {
    if(data.undeleted == 0) {
        alert('All ' + data.deleted + ' files delted from the server');
    } else {
        alert(data.deleted + ' files deleted and ' + data.undeleted + ' files could not be deleted');
    }
}, 'json');
