Replacing \r\n (newline characters) after running json_encode

Question

So when I run json_encode, it grabs the \r\n from MySQL aswell. I have tried rewriting strings in the database to no avail. I have tried changing the encoding in MySQL from the default latin1_swedish_ci to ascii_bin and utf8_bin. I have done tons of str_replace and chr(10), chr(13) stuff. I don't know what else to say or do so I'm gonna just leave this here....

$json = json_encode($new);
if(isset($_GET['pretty'])) {
echo str_replace("\/", "/", jsonReadable(parse($json)));
} else {
$json = str_replace("\/", "/", $json);
echo parse($json);
}

The jsonReadable function is from here and the parse function is from here. The str_replaces that are already in there are because I am getting weird formatted html tags like </h1>. Finally, $new is an array which is crafted above. Full code upon request.

Help me StackOverflow. You're my only hope

Does the string contain "\r\n" (as in 0x0D 0x0A) or the literal string '\r\n'? If it's the former, this should remove any newlines.

$json = preg_replace("!\r?\n!", "", $json);

Optionally, replace the second parameter "" with "<br />" if you'd like to replace the newlines with a br tag. For the latter case, try the following:

$json = preg_replace('!\\r?\\n!', "", $json);
