用PHP编写TXT文件，想要添加实际的换行符

I am writing a TXT file using PHP. I want to insert actual line breaks into the TXT file wherever necessary. I have tried all combinations of \n \r \r\n \n\r ... but these are not causing any linebreaks to appear - in most cases, I am seeing the text "\n" appear in the TXT file, with no linebreak.

我正在使用PHP编写TXT文件。我想在必要时在TXT文件中插入实际的换行符。我已经尝试过\ n \ r \ r \ n \ n \ n \ r \ n的所有组合......但是这些并没有导致出现任何换行符 - 在大多数情况下,我看到文本“\ n”出现在TXT文件中,没有换行。

I have also tried chr(13).

我也试过chr(13)。

Any other ideas would be appreciated.

任何其他想法将不胜感激。

Sounds to me like you might be using single quotes, i.e. '\n' rather than "\n".

听起来像你可能使用单引号,即'\ n'而不是“\ n”。

If you wanted to continue with a single quotes bias (as you should!), two options:

如果你想继续使用单引号偏差(正如你所希望的那样!),有两个选择:

file_put_contents('/path/to/file.txt', 'Hello friend!
This will appear on a new line.
As will this');

// or

file_put_contents('/path/to/file.txt', 'Hello friend!'."\n".'This will appear on a new line.'."\n".'As will this');

#2

For "\n" to work, you need to use double quotes, not '\n'.

要使“\ n”起作用,您需要使用双引号,而不是'\ n'。

But you should use the constant PHP_EOL instead, so that it adapts automatically to the OS ("\n", "\r" or "\r\n").

但是你应该使用常量PHP_EOL,以便它自动适应OS(“\ n”,“\ r”或“\ r \ n”)。

file_put_contents('file.txt', 'Bla' . PHP_EOL . 'Bla');

#3

\r\n in a windows server \n in linux Make sure you upload the file as ASCII.

\ r \ n在Windows服务器上\ n在linux中确保将文件上传为ASCII。

#4

You must write \n in a double-quoted string (in single-quoted strings no parsing takes place):

您必须在双引号字符串中写入\ n(在单引号字符串中不进行解析):

"foo\r\nbar"

you could also use chr(10) which is line break.

你也可以使用chr(10)这是换行符。
