我正在构建一个简单的博客平台。我正在建立这个人的人是盲人，并要求解决方案。他建议，因为他已经能够使用outlook，所以如果他只是通过电子邮件发送特定的电子邮件地址并自动插入数据库就很好。
这是我到目前为止（我每10分钟使用一个cronjob执行此脚本）：
include('Imap.php');
$date = date('d-M-y', strtotime('1 day ago'));
$term = 'ALL UNDELETED SINCE "'.$date.'"';
//ignore array of emails
$exclude = [];
$email = 'email@email.com'
$password = 'mypassword';
$host = 'mymailhost'//your email host
$port = '0000'//port number
$savePath = "emails";//folder to save attachments
$delete = true;//set to true to delete email
//initialise email
$imap = new Imap($email, $password,$host,$port, 'Inbox', $savePath, $delete);
//get emails pass in the search term and exclude array
$emails = $imap->emails($term, $exclude);
foreach($emails as $email)
{
$stmt = $db->prepare('INSERT INTO blog_posts (postTitle,
postDesc,postCont,postDate) VALUES (:postTitle, :postDesc, :postCont,
:postDate)') ;
$stmt->execute(array(
':postTitle' => $email['subject'],
':postDesc' => substr($email['body'], 0, 200),
':postCont' => $email['body'],
':postDate' => date('Y-m-d H:i:s')
));
}
我也有一个Imap类：

// Connect to a remote imap server
if ($port != '143') {
$this->secure = 'ssl/';
}
$this->connection = "{{$host}:{$port}/imap/{$this->secure}novalidate-cert}$folder";

我还有一个带有我的数据库连接的config.php文件。我无法让它工作
我是初学者，请一定帮忙。
更新：
所以我设法解决了一些错误。我现在通过cron作业获得输出。这是最新的：
