newline in json_encode() output
<p>I am building an output array like so</p>

<pre><code>            if (count($errors)) {
                $success = 'false'; 
                $output['json_msg'] = "Please try your submission again.";
                $output['errors'] = $errors;
            } else {
                $success = 'true';  
                $output['json_msg'] = "Thanks for Becoming a NOLA Insider!";
            }

            $output['success'] = $success;

            header('Content-type:application/json;charset=utf-8');
            if (count($errors)) { http_response_code(500); }
            echo json_encode($output);          
            exit;
</code></pre>

<p>But when I look at the response in Chrome's Network pane of the developer tools I see what appears to be a newline in response:</p>

<p><a href="https://i.stack.imgur.com/yqoHO.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yqoHO.jpg" alt="developer console screenshot"></a> </p>

<p>I tried wrapping json_encode() in trim() but this gave garbled output.</p>

<p>How do I eliminate the carriage return?</p>
