imap_delete — Mark a message for deletion from current mailbox

说明

imap_delete ( resource $imap_stream , int $msg_number [, int $options = 0 ] ) : bool

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: 由 imap_open() 返回的 IMAP 流。
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

Example #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

Note:

IMAP mailboxes may not have their message flags saved between connections, so imap_expunge() should be called during the same connection in order to guarantee that messages marked for deletion will actually be purged.
