$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.
imap由 imap_open() 返回的 IMAP 流。
reference
reference should normally be just the server
specification as described in imap_open()
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。
contentThe searched string
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.
