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');
