title: Remove Content-Type header from Lighttpd response
body: <p>I have written a function called IO::stdout:</p>
  
  <pre><code>class IO {
        public static function stdout($var) {
            $stdout = fopen('php://stdout', 'w');
            fwrite($stdout, $var, strlen($var));
            fclose($stdout);
        }
  }
  IO::stdout("Hello World!");
  </code></pre>
  
  <p>Well, it works! But when I request the page, it displays me:</p>
  
  <pre><code>Hello World!
  X-Powered-By: PHP/5.6.13
  Content-type: text/html; charset=UTF-8
  </code></pre>
  
  <p>Setting <code>expose_php = Off</code> in php.ini removed the X-Powered-By header, but the Content-Type header is still printed. It is probably added by Lighttpd. How do I disable the Content-Type header?</p>
