# imap_delete

(PHP 3, PHP 4, PHP 5)

imap_delete -- Mark a message for deletion from current mailbox

## 说明

bool imap_delete ( int imap_stream, int msg_number [, int options] )

Marks messages listed in `msg_number` for deletion. Messages marked for deletion will stay in the mailbox until either imap_expunge() is called or imap_close() is called with the optional parameter `CL_EXPUNGE`.

## 参数

`imap_stream`

  An IMAP stream returned by imap_open().

`msg_number`

  The message number

`options`

  You can set the `FT_UID` which tells the function to treat the `msg_number` argument as an `UID`.

## 返回值

Returns `TRUE`.

## 范例

例 1. imap_delete() example

`<?php
$mbox = imap_open("{imap.example.org}INBOX", "username", "password")
or die("Can't connect: " . imap_last_error());
$check = imap_mailboxmsginfo($mbox);
echo "Messages before delete: " . $check->Nmsgs . "<br />\n";
imap_delete($mbox, 1);
$check = imap_mailboxmsginfo($mbox);
echo "Messages after delete: " . $check->Nmsgs . "<br />\n";
imap_expunge($mbox);
$check = imap_mailboxmsginfo($mbox);
echo "Messages after expunge: " . $check->Nmsgs . "<br />\n";
imap_close($mbox);
?>`

## 注释

> 注意: POP3 mailboxes do not have their message flags saved between connections, so imap_expunge() must be called during the same connection in order for messages marked for deletion to actually be purged.
