Php-imap: 连接时出现 Kerberos 错误

为了解决我的问题，可以在执行与服务器的连接时禁用 GSSAPI 身份验证：

$imapStream = @imap_open($this->imapPath, $this->login, $this->password, 0, 0, array('DISABLE_AUTHENTICATOR' => 'GSSAPI'));

谢谢@tchemineau ，7 年后，你救了我的屁股，我不知道还有多少小时！！！ 🥳

您可以使用函数setConnectionArgs($options = 0, $retriesNum = 0, $params = null)设置这些参数：

<?php

    require_once __DIR__ . '/../vendor/autoload.php';
    use PhpImap\Mailbox;
    use PhpImap\Exceptions\ConnectionException;
    use PhpImap\Exceptions\InvalidParameterException;

    $mailbox = new Mailbox(
        '{imap.gmail.com:993/imap/ssl}INBOX', // IMAP server and mailbox folder
        '[email protected]', // Username for the before configured mailbox
        '*********', // Password for the before configured username
        __DIR__, // Directory, where attachments will be saved (optional)
        'US-ASCII' // Server encoding (optional)    
    );

    try {
        $mailbox->setConnectionArgs(0, 0, array('DISABLE_AUTHENTICATOR' => 'GSSAPI'));
    } catch(InvalidParameterException $ex) {
        die("Failed to set connection arguments: " . $ex->getMessage());
    }

    try {
        $mail_ids = $mailbox->searchMailbox('UNSEEN');
    } catch(ConnectionException $ex) {
        die("IMAP connection failed: " . $ex->getMessage());
    } catch (Exception $ex) {
        die("An error occured: " . $ex->getMessage());
    }

    foreach ($mail_ids as $mail_id) { ... }
