Add error message for missing/invalid header (#1017) 

* add error message for missing/invalid header

* Code cleanup

- simplify the check
  - do not invert the result of `preg_match()`
  - do not set the `$result` in loop, it is already set after the loop
- fix the order of code, first set `$this->error` then `$result`
