Strange problem with overlapping names

Hi all, the page shown below works fine on my own machine, but on another (remote) server, it gives me a strange result. Here's what happens: The first time I view the page it says "array(0) { }" as I'd expect, but on the second it says "object(kurv)(0) { }" where I expected another array. The problem seems to be that the object has the same name as the key in $_SESSION -- if I call it $foobar the problem disappears. But that explanation doesn't really make much sense to me. As I see it there's something wrong on the server. Can anybody tell me anything about this problem? Thanks, Niels <?php class kurv { function kurv() { if (!array_key_exists('kurv', $_SESSION)) {$_SESSION['kurv']=array();} } } session_start(); $kurv=new kurv(); var_dump($_SESSION['kurv']); ?>
