php - 使用 imap 和 php 检索最近的 3 封电子邮件

Question

我正在尝试弄清楚如何使用 imap 和 php 获取最新的 3 封电子邮件(SEEN 和 UNSEEN)。它需要资源高效，因为邮箱内部有 1000 封电子邮件。我认为获取所有 header 可能需要太多资源。

我只需要发件人、主题和日期...

有什么想法吗？感谢任何 syggestion/help/explaination/hint...

我是这样做的:

$mbox = imap_open("{imap.myconnection.com:993/imap/ssl}INBOX", "username", "password");

// get information about the current mailbox (INBOX in this case)
$mboxCheck = imap_check($mbox);

// get the total amount of messages
$totalMessages = $mboxCheck->Nmsgs;

// select how many messages you want to see
$showMessages = 5;

// get those messages    
$result = array_reverse(imap_fetch_overview($mbox,($totalMessages-$showMessages+1).":".$totalMessages));

// iterate trough those messages
foreach ($result as $mail) {

    print_r($mail); 

    // if you want the mail body as well, do it like that. Note: the '1.1' is the section, if a email is a multi-part message in MIME format, you'll get plain text with 1.1
    $mailBody = imap_fetchbody($mbox, $mail->msgno, '1.1');

    // but if the email is not a multi-part message, you get the plain text in '1'
    if(trim($mailBody)=="") {
        $mailBody = imap_fetchbody($mbox, $mail->msgno, '1');
    }

    // just an example output to view it - this fit for me very nice
    echo nl2br(htmlentities(quoted_printable_decode($mailBody)));
}

imap_close($mbox);
