imap_getmailboxes

Description

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.

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.

<?php
$mbox = imap_open("{imap.example.org}", "username", "password", OP_HALFOPEN)
      or die("can't connect: " . imap_last_error());
 
$list = imap_getmailboxes($mbox, "{imap.example.org}", "*");
if (is_array($list)) {
    foreach ($list as $key => $val) {
        echo "($key) ";
        echo imap_utf7_decode($val->name) . ",";
        echo "'" . $val->delimiter . "',";
        echo $val->attributes . "<br />\n";
    }
} else {
    echo "imap_getmailboxes failed: " . imap_last_error() . "\n";
}
 
imap_close($mbox);
?>
