PHP "define" and escaped characters

Question

Is there a way to insert an escaped character for carriage return in a define() statement?

define('MODULE_PAYMENT_PAYPALWPP_MARK_BUTTON_TXT', 
       "WSW uses PayPal as its primary merchant card account vendor./r
        You can check out with PayPal without the use of a PayPal account.");

I attempted the above statement but it will only out put the /r as literal.

You have to use double quotes around the defined string - but use "\n" instead -- The "\n" and "\r" really only work when you are using the script via php-cli or some equivalent.

If you are rendering this in/echoing to HTML, you'll have to use <br>

But, while you're at it, if you inspect the source via Ctrl+U or view-source: - then you'll see that your "\n" (I think "\r" may be the legacy version) - does, in fact appear as a line break.

Example:

echo "The quick brown fox <br> jumped over the lazy dog"; 
echo "The quick brown fox \n jumped over the lazy dog";

Try running that, and it'll make sense.

However, on inspecting the source the break is there and it is shown as a new line in the source but that is not being reflected on the actual page. – Curtis Adams Nov 12 '14 at 01:47
Exactly -!- You see, in the answer you accepted, the guy used `nl2br` which literally translates the `\n` to a `
` -- because in HTML, it will not break the line unless you tell it to... for the same reason that if you have a
tag, press enter a bunch of times, the browser still renders it all on the same line.

You need to change /r to \r (or \n - why see here)

If you want to echo it, you can simply use nl2br function:

echo nl2br(MODULE_PAYMENT_PAYPALWPP_MARK_BUTTON_TXT);

Wow, I don't know if I need another drink or sleep. – Curtis Adams Nov 12 '14 at 01:46
I'd go for the drink! :) Cheers! Feel free to mark the answer as correct. – baao Nov 12 '14 at 01:47
Unfortunately it only solved part of the issue. Now I can look at the source code and it shows the break but it is not being reflected on the actual page. Could that be due to a css setting? – Curtis Adams Nov 12 '14 at 01:50
Only thing I can imagine it's due to a css setting, when printing the line in a fresh page without any css appended it prints the line break. – baao Nov 12 '14 at 01:52
Thanks Michael. I will dig into the css. – Curtis Adams Nov 12 '14 at 01:54
