将邮件从回收站移至收件箱Gmail PHP Imap

Question

在使用IMAP和PHP之前，我从未尝试过获取和移动电子邮件，因此将发送到垃圾箱的电子邮件移回收件箱。

好的，所以我可以正确地从Gmail中提取电子邮件，我可以删除它们，或者将它们移到垃圾箱。

当我尝试将它们移回收件箱时，我收到以下错误：

注意：未知：[TRYCREATE]第0行未知中没有文件夹[Gmail]/收件箱（失败）（errflg=2）

所以很明显，有些事情我不太明白，在过去的几个小时里，我一直在网上和stackoverflow上寻找答案，但没有运气。有人知道为什么这个特定的行动没有成功吗？

任何帮助都像往常一样非常感谢，我很乐意掌握这个窍门，让自己成为一个小电子邮件应用程序。

下面是我创建的类，请参见方法undo（），这就是弹出此特定警告的地方。

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 {

        $this->emailarray.= '<div id="accordion">';

        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])) {

                $message = imap_fetchbody($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.= '<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

我发现，如果我连接到废纸篓，然后使用星号来获取最后一条消息，它就会按预期工作。

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);
}
