title: Control Operator Misused
body: <p>I've got some PHP download script. Its last two lines are these:</p>
  
  <pre><code>header("Content-Length: ".  @filesize($filename));
  @readfile($filename);
  </code></pre>
  
  <p>NetBeans warns in both lines "Error Control Operator Misused". May I ignore this warning or how can I fix it?</p>
