function function_dump($funcname) {
  try {
 
    if(is_array($funcname)) {
      $func = new ReflectionMethod($funcname[0], $funcname[1]);
      $funcname = $funcname[1];
    } else {
      $func = new ReflectionFunction($funcname);
    }
     
  } catch (ReflectionException $e) {
    echo $e->getMessage();
    return;
  }
 
  $start = $func->getStartLine() - 1;
 
  $end = $func->getEndLine() - 1;
 
  $filename = $func->getFileName();
 
  echo "function $funcname defined by $filename($start - $end)\n";
}
