在IMAP服务器上将电子邮件设置为SEEN

问题描述

我正在尝试从Imap服务器（Gmail）读取邮件。我会检查是否有新邮件（看不见）并进行查看。
我写了这段代码，但

I am trying to read mail from an Imap Server (Gmail). I would check if there are new mail (unseen) and check it as seen.I wrote this code but

imap_setflag_full

似乎不起作用。
如果我有一封新邮件，该脚本无法放置SEEN标志，并回显我总是有一封看不见的邮件。

seems to not work. If I have a new mail the script is unable to put the SEEN flag and it echo me that there is always one unseen mail.

  $mbox=imap_open( "{imap.gmail.com:993/ssl/novalidate-cert}" , $this->username, $this->password);
    if ($mbox) 
            {  echo "Connected\n<br><br>"; 
            }  else { exit ("Can't connect: " . imap_last_error() ."\n");  echo "FAIL!\n";  }; 

        if ($hdr = imap_check($mbox)) {
          $msgCount = $hdr->Nmsgs;
          echo "There are ".$msgCount." mail";
        } else {
          echo "Failed to get mail";

        }

        $result = imap_search($mbox, 'UNSEEN');
        echo "<br>Result: ";
        print_r($result);
        if($result==false)
            echo "No email";
        else{
            echo "you have mail"; 
            echo("<br>now I set the Seen flag for this mail");
            rsort($result);
            $status = imap_setflag_full($mbox, "1", "\\Seen \\Flagged", ST_UID);      
        }

        echo"<br><br>";


        $result = imap_search($mbox, 'UNSEEN');
        echo "<br>Result: ";
        print_r($result);
        if($result==false)
            echo "no mail";
        else{
            echo "there are still"; 

        }

非常感谢。

推荐答案

我认为问题在于硬编码的 1。我将 1替换为：

I think the problem is with the "1" you have hardcoded. I replaced the "1" with:

foreach ($result as $mail) {
    $status = imap_setflag_full($mbox, $mail, "\\Seen \\Flagged", ST_UID);
}

似乎有效。使用ST_UID时，实际上意味着一个ID，而不是序列号。

and it seems to work. When using ST_UID, this means actually an ID, and not a sequence number.
