# imap_lsub

(PHP 4, PHP 5, PHP 7)

imap_lsub — List all the subscribed mailboxes

### Description

imap_lsub ( resource `$imap_stream` , string `$ref` , string `$pattern` ) : array

Gets an array of all the mailboxes that you have subscribed.

### 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.

### Return Values

Returns an array of all the subscribed mailboxes.
