【问题描述】：
我使用 TCPDF 作为附件发送 pdf。我确实收到了电子邮件，所以电子邮件有效，但没有附件。
在电子邮件中，我收到了一条很长的乱码。如果我删除$data（如下面的代码），消息的内容会少得多，但仍然没有附件。

更新
我进行了一些更改，现在可以接收附件，但由于错误而无法打开附件
除了附件，邮件中没有其他内容。

【问题讨论】：
-
你不应该调用$pdf->输出两次，$fileatt 是一个字符串不是文件，它已经base64编码了
-
@nogad 谢谢。多么菜鸟的错误啊。我在我的代码中更改了它（删除了第一个）。还是不行
-
您仍在尝试以字符串形式打开文件并对其进行编码，即使它已经编码
-
@nogad 我没有关注？我应该改变什么？
