Create Carriage Return in PHP String?
提问by Brett Powell
We have written a small PHP Hook for our billing system that opens a new support ticket with us when an order is placed. It works except that for the "Open Ticket" API function, it takes a string for the message, but we cannot figure out how to put carriage returns in it.
我们为我们的计费系统编写了一个小的 PHP Hook，在下订单时向我们打开一个新的支持票。除了“Open Ticket”API 函数需要一个字符串作为消息之外，它是有效的，但我们无法弄清楚如何在其中放置回车符。
I have tried
我试过了
<p>, <br>, \n, \r\n, etc.
As it appears to just be completely plain text though, all of these are just being read verbatim rather than made into carriage returns.
由于它似乎只是完全纯文本，因此所有这些都只是逐字阅读而不是回车。
Does anyone have any thoughts on how this could be done? http://docs.whmcs.com/API:Open_Ticket
有没有人对如何做到这一点有任何想法？ http://docs.whmcs.com/API:Open_Ticket

Carriage return is "\r". Mind the double quotes!
回车是"\r"。注意双引号！
I think you want "\r\n"btw to put a line break in your text so it will be rendered correctly in different operating systems.
我认为您希望"\r\n"btw 在您的文本中放置一个换行符，以便它可以在不同的操作系统中正确呈现。
- Mac: \r
- Linux/Unix: \n
- Windows: \r\n
- 苹果机：\r
- Linux/Unix：\n
- 视窗：\r\n

There is also the PHP 5.0.2 PHP_EOL constant that is cross-platform !
还有跨平台的 PHP 5.0.2 PHP_EOL 常量！

$postfields["message"] = "This is a sample ticket opened by the API\rwith a carriage return";
回答by Themer
PHP_EOL returns a string corresponding to the line break on the platform(LF, \n ou #10 sur Unix, CRLF, \n\r ou #13#10 sur Windows).
PHP_EOL 返回与平台上的换行符对应的字符串（LF, \n ou #10 sur Unix, CRLF, \n\r ou #13#10 sur Windows）。
echo "Hello World".PHP_EOL;

Fragment PHP (in console Cloud9):
片段 PHP（在控制台Cloud9 中）：
echo "\n";
echo "1: first_srt=1\nsecnd_srt=2\n";
echo "\n";
echo '2: first_srt=1\nsecnd_srt=2\n';
echo "\n";
echo "==============\n";
echo "\n";
resulting output:
结果输出：
1: first_srt=1
secnd_srt=2
2: first_srt=1\nsecnd_srt=2\n
==============
Difference between 1 and 2: "versus '
1 和 2 之间的区别： "与'
