imap_listscan

(PHP 4, PHP 5, PHP 7, PHP 8)

imap_listscan — Returns the list of mailboxes that matches the given text

Description

imap_listscan(
    IMAP\Connection $imap,
    string $reference,
    string $pattern,
    string $content
): array|false

Returns an array containing the names of the mailboxes that have content in the text of the mailbox.

This function is similar to imap_listmailbox(), but it will additionally check for the presence of the string content inside the mailbox data.

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.
