如果PHP IMAP的文件名包含星号，则无法获取附件

我正在使用IMAP通过读取邮箱来进行一些数据输入。除了附件文件名包含星号（*）字符的一个实例外，该代码几乎适用于所有电子邮件，在这种情况下，代码无法获取文件（或者更准确地说，PDF附件不可读）

我为获取电子邮件内容（包括获取PDF附件）而编写的代码是：

尽管如此，我仍然可以将所有信息（标题、文件名等）保存到数据库中，但由于某种原因，只有保存到服务器上的文件是不可读的（见附图）

以前有人遇到过这种情况吗

您是否使用传统的电子邮件客户端下载附件并确保其格式正确？目前我正在使用cPanel webmail（Horde）下载电子邮件。有趣的是，当它下载到我的Windows计算机上时，文件名会自动从

*MEA-发票号91135811*

更改为

\u MEA-发票号91139748

（星号改为下划线），然后可读。我假设IMAP无法解析的文件名有问题？您是否使用传统的电子邮件客户端下载附件并确保其格式正确？目前我正在使用cPanel webmail（Horde）下载电子邮件。有趣的是，当它下载到我的Windows计算机上时，文件名会自动从
