将电子邮件发送到解析器脚本时出现“参数 1 中的错误，字符 3：未找到选项”

Question

当我尝试发送符合条件的电子邮件以将电子邮件传输到我的 php 脚本时，出现错误。 错误是：

pipe to |/home/**********/**********/script.php
  generated by f1c8f287-02ea81a3-11a218b30839@**********.com

The following text was generated during the delivery attempt:

我不想让这个问题不必要地冗长......

这是我的完整 script.php 代码以防万一：

//$conn = mysqli_connect($dbHost, $dbUser, $dbPass, $dbName) or die(mysqli_error($conn));

我遵循了这些规则，它们受到了检查：

1. 文件权限（及其目录）设置为 0755

2. 通过 cPanel 上传。 该文件应为 ascii 格式而不是二进制格式（我不知道如何检查）

3. 在 php 标签和 hashbang 之前/之后没有空格/换行符

我查看并尝试了这些类似问题的答案，但没有解决我得到的错误：

其中包括 cPanel 论坛和其他资源。

此问题的解决方案是确保为 Unix 保存脚本的行尾。 如果您使用的是 Windows，请检查您的文本编辑器用于保存行尾的默认设置。 相关问题证明在处理这个问题时很有用， How do configure sublime to always convert to unix line endings on save?

对于 Sublime Text 3，我只是更改了行尾格式（菜单 > 视图 > 行尾 > Unix）并保存了文件。 电子邮件解析器现在可以正常工作。

这个出色的解决方案归功于 Triplee。 对于未来的读者，如果您是 Windows 用户，一般故障排除论坛会提到无关的回车符，但不会提及将文本格式化为 Unix 行结尾的任何内容。
