Create Carriage Return in PHP String?

问题:

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.

I have tried

<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.

Does anyone have any thoughts on how this could be done? http://docs.whmcs.com/API:Open_Ticket

回答1:

Carriage return is "\r". Mind the double quotes!

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.

• Mac: \r
• Linux/Unix: \n
• Windows: \r\n

There is also the PHP 5.0.2 PHP_EOL constant that is cross-platform !

回答3:

$postfields["message"] = "This is a sample ticket opened by the API\rwith a carriage return";

Fragment PHP (in console Cloud9):

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:

  1: first_srt=1
  secnd_srt=2

  2: first_srt=1\nsecnd_srt=2\n
  ==============

Difference between 1 and 2: " versus '

I find the adding <br> does what is wanted.

回答6:

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).

echo "Hello World".PHP_EOL;
