“\n”收不到 OUTLOOK 电子邮件
$str = "Hello Jagdish \n\n";
$str .= "this is nice evening \n\n";
$str = stripcslashes($str);
mail($to, $subject, $message);
在 Outlook 中查看此电子邮件时，没有出现“\n\n”
原因是什么？
如何在电子邮件中获取这些内容？
$str = "Hello Jagdish \n\n";
$str .= "this is nice evening \n\n";
$str = stripcslashes($str);
mail($to, $subject, $message);

Outlook 会根据需要重新设置纯文本电子邮件的格式。可以在选项中关闭此功能，但如果您以纯文本形式向客户发送内容，则对此无能为力。
其理论是，它试图检测固定宽度的列，并删除固定宽度，以使电子邮件更具可读性。根据我的经验，这只会产生烦恼，正如您所经历的那样。
如果您要发送电子邮件的 HTML 版本，它将被正确使用和格式化。 （请注意，对于无法使用 HTML 版本的客户端，除 HTML 版本外，您还应始终发送纯文本版本。Outlook 默认情况下使用 HTML 版本（如果存在）。）
Outlook re-formats plain-text e-mails as it sees fit. This can be turned off in the options, but if you are sending stuff to your customers in plain-text, there is nothing that can be done about this.
The theory is that it is trying to detect a fixed-width column, and remove the fixed-width so the e-mail is more readable. In my experience, this simply produces annoyance, as you are experiencing.
If you were to send an HTML version of your e-mail, it would be used and formatted correctly. (Note that you should always send a plain-text version in addition to the HTML version, for clients that can't use the HTML version. Outlook uses the HTML version by default, if it exists.)
Outlook 会自动删除纯文本电子邮件中的换行符。
如果确实如此，它会告诉您（至少 Outlook 2003 是这样），并且您可以选择恢复它们。
Outlook removes linebreaks automatically in plain text e-mails.
If it does, it tells you so (well, at least Outlook 2003 did) and you got the option to restore them.
我在使用 \n 和生成纯文本电子邮件时遇到了同样的问题（在 Java 中）。这很烦人，因为对我来说使用 2 \n 添加了两行新行，所以我可以做零或两行新行，但不能做一行。
我尝试了 \r\n 但似乎没有成功。
我想出了一个解决我问题的方法。我只是在行尾之后和 \n 之前添加了一堆空格。我发现我需要 3 个空间才能正常工作。
body += "单词单词单词\n";
因为我的行有 57 个字符长（不含空格），所以我假设 Outlook 合并了少于 60 个空格的行 (57 + 3 = 60)。 Outlook 让我这样做很糟糕，但它对我有用！
I'm having the same issue (in Java) generating plain text emails using \n and. It was annoying because using 2 \n's for me added both new lines, so I could do zero or two new lines but not one.
I tried \r\n but it didn't seem to do the trick.
I figured out a hack that fixed my problem. I just added a bunch of spaces after the end of the line and before the \n. I figured out that I needed exactly 3 spaces for it to work.
body += "words words words \n";
Because my line was 57 chars long without the spaces, I'm assuming that outlook is combining lines that have less than 60 spaces (57 + 3 = 60). Outlook is terrible for making me do this but it worked for me!
Windows 使用
\r\n换行符，请尝试将每个\n替换为\r\n。另外，您需要删除
$str = stripcslashes($str);因为它将\n转换为nWindows uses
\r\nline breaks, try replacing every\nwith\r\n.Also, you need to remove
$str = stripcslashes($str);as it converts\ninton
