Re: possible variable declaration error

Correct me if I wrong, but you're declaring $id AFTER binding the SQL parameter, therefore your :id isn't being bound to anything, hence the empty returned array.

I think:
$d_series_fetch = $db->prepare("SELECT * FROM defaultseries WHERE publisher >> :id");
$id = 'DC Comics';
$d_series_fetch->bindParam(':id',$id);

*should* work.
