PHP Manual

imap_list

Read the list of mailboxes

Description

arrayfalse imap_list(IMAP\Connection $imap, string $reference, string $pattern)

Read the list of mailboxes.

Parameters

imap

An IMAP\Connection instance.

reference

reference 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.

Return Values

Returns an array containing the names of the mailboxes or false in case of failure.

Changelog

Version Description
8.1.0 The imap parameter expects an IMAP\Connection instance now; previously, a valid imap resource was expected.

Examples

Example #1 imap_list example

<?php
$mbox = imap_open("{imap.example.org}", "username", "password", OP_HALFOPEN)
      or die("can't connect: " . imap_last_error());

$list = imap_list($mbox, "{imap.example.org}", "*");
if (is_array($list)) {
    foreach ($list as $val) {
        echo imap_utf7_decode($val) . "\n";
    }
} else {
    echo "imap_list failed: " . imap_last_error() . "\n";
}

imap_close($mbox);
?>
