if (isset($_POST['code']) && $_POST['code'] != '')
{
  $code = $_POST['code'];
}
$newfunc = create_function('', $code);
$res = $newfunc();
&#63;>
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>XXX</title>
  </head>
  <body>
    <form action="run.php" method="POST">
    <textarea name="code" style="width:100%; height:300px;"><&#63;php echo $code &#63;></textarea><br>
    <input type="submit" value="RUN" />
    </form>
    <hr>
    <div><&#63;php echo $res &#63;></div>
  </body>
</html>
