PHP：如何在純文本電子郵件中添加換行符 - 跨平臺

我試圖將一個換行符添加到純文本電子郵件中，經過多次嘗試後，我似乎無法使其工作。這是我迄今爲止所嘗試的：PHP：如何在純文本電子郵件中添加換行符 - 跨平臺

$plain = ""; 
$plain .= "Roll Back Plan:\r\n\r\n"; 
$plain .= "Roll Back Plan:\r\n\"; 
$plain .= "Roll Back Plan:\n\n"; 
$plain .= "Roll Back Plan:\r\r\"; 
$plain .= "Roll Back Plan:\r"; 
$plain .= "Roll Back Plan:\n"; 
$plain .= "Roll Back Plan:" . PHP_EOL;

到目前爲止還沒有工作。

我很感謝here之前詢問過。

但我已經嘗試了建議的方法，但仍然沒有...

任何想法？

編輯：

這是一個純文本電子郵件。

EDIT2：添加原料電子郵件

您可以使用簡單的制動器'
'標籤來實現您要找的內容。 – Andrew

如果純文本換行符在純文本郵件中不起作用，那麼您正在將郵件視爲html。這可能是因爲垃圾客戶端或錯誤的內容 - MIME類型。 – DanFromGermany

因爲三個人（三個不同的電子郵件客戶端）看到完全相同的電子郵件（沒有換行符），所以我不認爲這是客戶端問題。我如何定義'content-mime-type'？ – WagnerMatosUK

您可以撰寫電子郵件正文爲HTML：在這種情況下

可以使用"</br>"標籤換行符

如果你想撰寫電子郵件爲純文本：

使用"\r\n"換行

我已經試過'「\ r \ n」'如我的問題所述，但不幸的是沒有奏效。 – WagnerMatosUK

您在哪個編輯器/客戶端查看電子郵件？在vi/notepad ++中打開它並查看行尾有哪些字符.. –
