Then later that day I wrote:

I did some more investigating. Your problem appears to be PHP5 specific.
I manually created the serialize string I assumed you had, but PHP4 was
smarter than me and auto converted the string key to an integer once
again; however, PHP5 for some reason during unserialization maintained
the string type for the key, however it was not able to access the value
because upon attempting to access the value I'm assuming it did a type
conversion to integer... additionally I got the following error notice
when trying to access the value:
<b>Notice</b>: Undefined index: 0 in <b>/home/suds/foo.php</b> on line
<b>25</b><br />
NULL
The following can duplicated the error:
$ser = 'a:1:{s:1:"0";s:3:"foo";}';
$unser = unserialize( $ser );
var_dump( $unser );
var_dump( $unser['0'] );
Cheers,
Rob.
