PHP echo the equivalent of CR LF of Notepad
提问by troc
I need to export some data using PHP and for each line I'm adding a \r\n. When I open the exported data file that I downloaded, I see that the \r\nis interpreted as [LF] in Notepad.
我需要使用 PHP 导出一些数据，并为每一行添加一个\r\n. 当我打开下载的导出数据文件时，我看到\r\n在记事本中被解释为 [LF]。
But the application in which I open the file doesn't read the [LF] as a new line.
但是我打开文件的应用程序不会将 [LF] 作为新行读取。
Now if I do a [CR][LF] in Notepad, the application can read the [CR][LF] as a new line.
现在，如果我在记事本中执行 [CR][LF]，应用程序可以将 [CR][LF] 作为新行读取。
How can I echo the equivalent of [CR][LF] with PHP?
如何使用 PHP 回显等效于 [CR][LF] 的内容？

Problem solved: the string was passed in the POST parameter. Removing the \r.
问题已解决：字符串在 POST 参数中传递。删除\r。
You just have to do a str_replace("\n", "\r\n", $...);.
你只需要做一个str_replace("\n", "\r\n", $...);.

It's as simple as doing:
这就像做一样简单：
echo "\r\n";
(note the double quotes)
（注意双引号）

Do echo PHP_EOL;
做 echo PHP_EOL;
That way it'll always display the correct linefeed/carriage return combination that's valid for the system you're on, since not all OSes use the same newline convention. (More information: PHP global constants.)
这样，它将始终显示对您所在系统有效的正确换行/回车组合，因为并非所有操作系统都使用相同的换行约定。（更多信息：PHP 全局常量。）
