array imap_getsubscribed ( resource $imap_stream , string $ref , string $pattern )
Gets information about the subscribed mailboxes. Identical to imap_getmailboxes(), except that it only returns mailboxes that the user is subscribed to.
Returns an array of objects containing mailbox information. Each object has the attributes name, specifying the full name of the mailbox; delimiter, which is the hierarchy delimiter for the part of the hierarchy this mailbox is in; and attributes. Attributes is a bitmask that can be tested against: LATT_NOINFERIORS - This mailbox has no "children" (there are no mailboxes below this one). LATT_NOSELECT - This is only a container, not a mailbox - you cannot open it. LATT_MARKED - This mailbox is marked. Only used by UW-IMAPD. LATT_UNMARKED - This mailbox is not marked. Only used by UW-IMAPD.
