我在网上找到了PHP代码，可以从这里使用IMAP将附件下载到目录。 http://www.nerdydork.com/download-pop3imap-email-attachments-with-php.html
我稍微修改了
$structure = imap_fetchstructure($mbox, $jk);
$parts = ($structure->parts);
到
$structure = imap_fetchstructure($mbox, $jk);
$parts = ($structure);
让它正常运行，否则我得到一个错误，关于stdClass如何定义一个名为$ parts的属性。这样做，我能够下载所有附件。我最近再次测试它，但它没有用。好吧，它没有工作6次，工作到第7次，然后没有工作。我认为这与我搞砸零件处理有关，因为count（$ parts）每条消息都会返回1，所以我认为它没有找到任何附件。
由于它在一个点上下载了附件而没有任何问题，因此我确信这个区域已经搞砸了就在这里。在此代码块之前是一个for循环，它遍历框中的每个消息，并且在循环之后，每个imap结构只需要通过$ parts。感谢您的任何帮助，您可以提供。我查看了php.net上的imap_fetchstructure页面，无法弄清楚我做错了什么。
编辑：我只是在输入我的问题后仔细检查了该文件夹，然后全部弹出。我觉得我疯了。我在开始输入这个代码之前几分钟就没有运行代码，而且对我来说没有意义，需要很长时间才能触发。我在邮箱中有大约800条消息，但我想，因为它在PHP的最后打印了我的语句，表明所有文件创建工作都已完成。
