php如何实现不借助IDE快速定位行数或者方法定义的文件和位置

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";
}

function_dump('get_affiliate');

function get_affiliate defined by d:wwwadminaffiliate.php(232 - 238)
