Description:
------------
The second argument (Tidy instance) is mandatory.

See http://php.net/tidy_getopt - Because the same arginfo from the method is reused, the global function has incorrect reflection signatures.

For the global functions, PHP 7.1 and newer are affected



https://github.com/php/php-src/pull/3439/files was an earlier, incorrect attempt at fixing this, before noticing that I needed to stop reusing arginfo and that additional methods such as tidy_repair_string() also had incorrect signatures.

- 

Test script:
---------------
var_export((new ReflectionFunction('tidy_getopt'))->getParameters());
// Same for tidy_get_root(), tidy_get_html(), tidy_get_head(), tidy_get_body(), tidy_repair_string(), and probably even more global functions

Expected result:
----------------
Expected: Both $option and $object should exist as required parameters on tidy_getopt.

The reflection signature of Tidy::getOpt(), etc. should not be changed by any bug fix.

Actual result:
--------------
Observed: Only one required parameter is rec

array (
  0 => 
  ReflectionParameter::__set_state(array(
     'name' => 'option',
  )),
)
