【问题描述】：
下午好，
我无法在从网站发送的电子邮件中发送附件，但它确实可以看到附件。如何将附件添加到发送的电子邮件中。 我确实看到如下文字：
--451b4ac97a84a2205e1d116ef096f765 内容类型：“图像/jpeg；名称=“testbeeld.jpg” 内容处置：附件；文件名="testbeeld.jpg" 内容传输编码：base64 X-附件-ID：66045
在我的身体里。 感谢您查看它。

【问题讨论】：
-
phpmailer 使用起来更容易
-
可能是的，但我不想使用 phpmailer。这以前有效，但发生了一些变化，我需要弄清楚是什么。
-
stackoverflow.com/questions/12301358/… 3 秒。在谷歌上 ;-)
-
我看到了那个帖子，在这里并没有真正帮助我。正如我所说，一切正常（它甚至可以看到文件名、类型和大小并将其发布在电子邮件中）。但是附件没有显示。 $encoded_content 显示为图像的巨大字符串。不是图像本身。
-
以该问答中的答案为例。如果它失败了，那么某些东西就失败了。确保表单没问题 - 使用错误报告 php.net/manual/en/function.error-reporting.php 看看是否有任何结果。
