我如何在 php 中使用 imap 显示或解码 gmail 内嵌图像或消息

如何解决我如何在 php 中使用 imap 显示或解码 gmail 内嵌图像或消息

我正在编写 PHP 脚本如何在 PHP 中使用 imap 显示或解码 gmail 内嵌图像或消息，目前它显示的是 decode code 而不是内嵌图像？

我如何使用 imap_fetchbody 检查消息的编码或显示内嵌图像（已经这样做了大约两个小时，所以丢失了）然后正确解码。

这是我的代码

 /* Connecting Gmail server with IMAP */
                                $connection = imap_open('{imap.gmail.com:993/imap/ssl/novalidate-cert}INBox',"$email","$password") or die('Cannot connect to Gmail: ' . imap_last_error());

                                /* Search Emails having the specified keyword in the email subject */
                                $emailData = imap_search($connection,'ALL');



                                if (! empty($emailData)) {
                                    foreach ($emailData as $emailIdent) {


                                        $z++;

                                        $overview = imap_fetch_overview($connection,$emailIdent,0);
                                        $message = imap_fetchbody($connection,1);
