New Lines inside DB dont get displayed in textarea - php

Question

Some strange behaviour with the same script on different Websites here. Here you go:
I have an textarea where users enter text. They also do newlines using enter. That is stored inside the mysql db like this:
Line One\r\nLine Two\r\n\r\nLine Three
The problem occures when displaying that text inside a textarea again.
In most cases everything works fine. The following is displayed inside the textarea:
Line One
Line Two
Line Three
On some websites however only the following is displayed inside the textarea:
Line One
Line Two
Line Three
Inside the db the two newlines (\r\n\r\n) are still there. Only one is displayed however.
This happens like i said only on some websites, in most cases multiple newlines like this \r\n\r\n are displayed fine.
UPDATE:
Seams like JSON has something to do with it. It is an JSON string containing a string like "Line One\r\nLine Two\r\n\r\nLine Three".
{"mystring":"Line One\r\nLine Two\r\n\r\nLine Three"}
$row = $db->load(); // get the json string
var_dump($row); // \r\n\r\n still inside!
$jrow = json_decode($row);
var_dump($jrow->mystring); // on some servers multiple newlines are chopped to one

Try using n2lbr when displaying the DB value in the textarea. Does that help at all? It's worked for me in the past.
