imap_listscan

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

imap_listscanReturns the list of mailboxes that matches the given text

说明

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.

参数

imap

An IMAP\Connection instance.

reference

reference should normally be just the server specification as described in imap_open()

警告

Passing untrusted data to this parameter is insecure, unless imap.enable_insecure_rsh is disabled.

pattern

指定在邮箱层级的何处开始查找。

在组成 pattern 的字符中可使用两个特殊字符: '*' 和 '%'。 '*' 是指返回所有邮箱目录. 如果将 '*' 作为 pattern 参数时, 则会返回整个邮箱层级结构。 '%' 是指只返回当前级次。 '%' 作为 pattern 参数则只会返回顶层邮箱; '~/mail/%' 用于 UW_IMAPD 则会返回名为 ~/mail 的目录, 但不包含其子目录。

content

The searched string

返回值

Returns an array containing the names of the mailboxes that have content in the text of the mailbox, 或者在失败时返回 false.

更新日志

版本 说明
8.1.0 The imap parameter expects an IMAP\Connection instance now; previously, a 资源(resource) was expected.
