You can try

throw new \Exception("error");

Edit, adding function for check exist file by use curl

function checkUrlExistFile($url): bool {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HEADER, true);
  curl_setopt($ch, CURLOPT_NOBODY, true);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
  curl_exec($ch);
  $info = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  curl_close($ch);
  if($info == '200') return true;
  return false;
}

And Example

if (!checkUrlExistFile($url)) {
  throw new \Exception("error");
}
