imap_lsub

Parameters

imap_stream

An IMAP stream returned by imap_open().

ref

ref should normally be just the server specification as described in imap_open()

Warning

Passing untrusted data to this parameter is insecure, unless imap.enable_insecure_rsh is disabled.

pattern

Specifies where in the mailbox hierarchy to start searching.

There are two special characters you can pass as part of the pattern: '*' and '%'. '*' means to return all mailboxes. If you pass pattern as '*', you will get a list of the entire mailbox hierarchy. '%' means to return the current level only. '%' as the pattern parameter will return only the top level mailboxes; '~/mail/%' on UW_IMAPD will return every mailbox in the ~/mail directory, but none in subfolders of that directory.
