將電子郵件發送到解析器腳本時出現“參數 1 中的錯誤，字符 3：未找到選項”

Question

當我嘗試發送符合條件的電子郵件以將電子郵件傳輸到我的 php 腳本時，出現錯誤。 錯誤是：

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

The following text was generated during the delivery attempt:

我不想讓這個問題不必要地冗長......

這是我的完整 script.php 代碼以防萬一：

?>

我遵循了這些規則，它們受到了檢查：

1. 文件權限（及其目錄）設置為 0755

2. 通過 cPanel 上傳。 該文件應為 ascii 格式而不是二進制格式（我不知道如何檢查）

3. 在 php 標簽和 hashbang 之前/之后沒有空格/換行符

我查看並嘗試了這些類似問題的答案，但沒有解決我得到的錯誤：

PHP電子郵件管道錯誤

其中包括 cPanel 論壇和其他資源。

此問題的解決方案是確保為 Unix 保存腳本的行尾。 如果您使用的是 Windows，請檢查您的文本編輯器用於保存行尾的默認設置。 相關問題證明在處理這個問題時很有用， How do configure sublime to always convert to unix line endings on save?

對於 Sublime Text 3，我只是更改了行尾格式（菜單 > 視圖 > 行尾 > Unix）並保存了文件。 電子郵件解析器現在可以正常工作。

這個出色的解決方案歸功於 Triplee。 對於未來的讀者，如果您是 Windows 用戶，一般故障排除論壇會提到無關的回車符，但不會提及將文本格式化為 Unix 行結尾的任何內容。
