將郵件從垃圾箱移動到收件箱Gmail PHP Imap

Question

在使用IMAP和PHP之前，我從來沒有玩過獲取和移動電子郵件的操作，因此，我對於將發送到垃圾箱的電子郵件移動回收件箱感到很困惑。

好的，所以我可以正確地從Gmail提取電子郵件，並且可以刪除它們，也可以將其移到回收站。

當我嘗試將其移回收件箱時，出現以下錯誤：

注意：未知：[TRYCREATE]在第0行的“未知”中沒有文件夾[Gmail] /收件箱（失敗）（errflg = 2）

所以很明顯，有些事情我還不太了解，在過去的兩個小時里，我一直在網上和stackoverflow上尋找答案，但是沒有運氣。 有誰知道為什么這個特定的動作不能成功？

與往常一樣，任何幫助都將受到贊賞，我很想擺脫這個困擾，並讓自己成為一個小小的電子郵件應用程序。

下面是我制作的類，請參見方法undo（），這是該特定警告彈出的地方。

class Gmail {

public $emailsexists = false;
public $emailarray = '';

private $username;
private $password;
private $inbox;


public function __construct($username,$password) {
    /* connect to gmail using imap */
    $hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
    $this->username = $username;
    $this->password = $password;
    /* try to connect using username and password set in core/init.php (gmail_credentials) */
    $this->inbox = imap_open($hostname,$this->username,$this->password) or die('Cannot connect to Gmail: ' . imap_last_error());
}

public function delete($email) {
    if ($email !== '' && is_numeric($email)) {
        if (imap_mail_move($this->inbox, $email, '[Gmail]/Trash')) {
            return true;
         } else {
            return false;
         }
    } else {
        return false;
    }
    imap_close($this->inbox);
}

public function undo($email) {
    if ($email !== '' && is_numeric($email)) {
        if (imap_mail_move($this->inbox, $email, '[Gmail]/Inbox')) { // FIX Throws back a warning
            return true;
        } else {

    $emails = imap_search($this->inbox,'UNSEEN');

    if($emails) {
        /* statement that tells that emails exist */
        $this->emailsexists = true;

        rsort($emails);

        $x = 0;
        /* Open up the accordion */
        $this->emailarray.= '<div id="accordion">';
        /* for every email... */
        foreach($emails as $email) {
            /* get information specific to this email */
            $overview = imap_fetch_overview($this->inbox,$email,0);
            $structure = imap_fetchstructure($this->inbox, $email);
            $message = imap_fetchbody($this->inbox,$email,1,FT_PEEK);
            if(isset($structure->parts) && is_array($structure->parts) && isset($structure->parts[1])) {
                $part = $structure->parts[1];
                $message = imap_fetchbody($this->inbox,$email,2,FT_PEEK);

            }
            /* escape and decode the mimeheaders */
            $subject = escape(str_replace("_"," ", mb_decode_mimeheader($overview[0]->subject)));
            /* decode and put the subject into the accordion header */
            $this->emailarray.= '<h3>'.html_entity_decode(escape($subject)).'</h3>';
            $this->emailarray.= '<div>';
            $this->emailarray.= '<div class="btn-group pull-right">';
            $this->emailarray.= '<a href="#" title="Reply" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-share-alt text-success"></span></a>';
            $this->emailarray.= '<a href="#" title="Forward" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-send text-success"></span></a>';
            $this->emailarray.= '<a href="index.php?task=delete&id='.$email.'" title="Delete" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-fire text-danger"></span></a>';
            $this->emailarray.= '</div>';
            $this->emailarray.= '<p>';
            /* decode the email body using the built in quoted_printable_decode function */
            $this->emailarray.= quoted_printable_decode($message);
            $this->emailarray.= '</p>';
            $this->emailarray.= '</div>';

            /* if the counter reaches a certain number, break out and continue the script */
            $x++;
            if ($number) {
                if ($x >= $number) {
                    break;
                }
            }

        }
        /* close off the accordion */
        $this->emailarray.= '</div>';


    /* If no emails are found return a message */
    } else {
        echo "No emails";
    }
    /* close the imap connection */
    imap_close($this->inbox);
}

}

Answer 1

我發現，如果我連接到垃圾箱，然后使用星號獲取最后一條消息，則該消息將按預期工作。

public function undo($email) {
    // check if message id exists and is numeric
    if ($email !== '' && is_numeric($email)) {
        // set hostname to trash
        $hostname = '{imap.gmail.com:993/imap/ssl}[Gmail]/Trash';
        $this->inbox = imap_open($hostname,$this->username,$this->password) or die('Cannot connect to Gmail: ' . imap_last_error());
        // return true if the message was moved
        if (imap_mail_move($this->inbox, '*', 'Inbox')) {
        return true;
        } else {
        return false;
        }
    } else {
    return false;
    }
    imap_close($this->inbox,CL_EXPUNGE);
}
