note 9938 added to imap_fetchstructure

i'm writing a mime parsing class, and workin on a member function to parse out all the info i need for an attachment. i'm workin with dparameters and parameters. they seem to be arrays of objects. the objects are MIME key-value pairings, like FILENAME-'filename.txt'. any idea why this is an array? when would there be more than one index? when there's two FILENAME attribs? thanks blake http://www.php.net/manual/function.imap-fetchstructure.php
