Cant get \n to work in php

Question

I'm trying to echo a string and the string contains "\n" and "\r" in it, but when it executes it still shows the "\n" and "\r".

Here is what I'm doing.

$url = 'http://whoiz.herokuapp.com/lookup.json?url=madithouse.com';
$response = file_get_contents($url);
echo $response;

It echos every thing as it is, all I want is that everywhere where it has "\n" it goes to new line.

@Ignacio The content that url returns, oddly enough, isn't JSON. — Bill Criswell, Dec 24 '13 at 12:22
@IgnacioVazquez-Abrams when I decode JSON it only removes the "\n" & "\r" what I want is when there is "\n" it moves to new line — Professor Haseeb, Dec 24 '13 at 12:23
Ignacio: I'm just getting a simple string. `json_decode()` does nothing to it. This also suggests is isn't http://stackoverflow.com/questions/7487869/is-this-simple-string-considered-valid-json so I'm confused. — Bill Criswell, Dec 24 '13 at 12:31

If you're outputting to a browser you won't see the new lines (unless you view source). You'd have to use nl2br().

In this case nl2br() doesn't work. If you want output in new line in place of "\n" just replace it with <br>.

Like this

$url = 'http://whoiz.herokuapp.com/lookup.json?url=madithouse.com';

$response = file_get_contents($url);

echo str_replace("\\n", "<br>", $response);
