title: Do I need to sanitize user data for error_log() in PHP?
body: <p>Do I need to sanitize user input from a public facing form when passing data straight into:</p>
  
  <pre><code>error_log();
  </code></pre>
  
  <p><a href="http://php.net/manual/en/function.error-log.php" rel="noreferrer">http://php.net/manual/en/function.error-log.php</a></p>
  
  <p>I know this is a rather simplistic question but I can't find anything elsewhere.</p>
  
  <p>Thanks</p>
