imap_getmailboxes -- Read the list of mailboxes, returning detailed information on each oneReturns 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.
Mailbox names containing international Characters outside the printable ASCII range will be encoded and may be decoded by imap_utf7_decode().
ref should normally be just the server specification as described in imap_open(), and pattern specifies where in the mailbox hierarchy to start searching. If you want all mailboxes, pass '*' for pattern.
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.
