php single quote issue

[CoenraadS]

if ($sysType == '') {
  return $c['view']->render($response->withStatus(404), '/error/404.php', [
    "myMagic" => "Let's roll"
  ]);
} else {
  return $c['response']
        ->withStatus(404)
        ->withHeader('Content-Type', 'text/html')
                                                ^ no punctuation token
        ->write('Page not found!');
}

Note the single quote in Let's roll affects 'text/html') later on

Let's roll

Lets roll (no apostrophe)
