Description:
------------
method_exists() in php74 works differently from php73 in checking private methods
versions used

php74 PHP 7.4.0RC3 (cli) (built: Oct  1 2019 08:30:29) ( NTS )

Test script:
---------------
class Base {

 public function __get($k) {
  $m = '_get_'.$k;
  if (!method_exists($this, $m)) throw new \Exception('no-property:'.$k);
  return $this->$m();
 }

 private function _get_a() { return 'a'; }

}

class Test extends Base {}

$x = new Test;
echo $x->a;
//php74 : PHP Fatal error:  Uncaught Exception: no-property-a in test.php
//php73 : prints a 

Expected result:
----------------
I expect both php73 and php74 printing "a"

note that _get_a() method is properly executed (when no check with "method_exists" is done) both by php73 and php74.

class Base {

 public function __get($k) {
  $m = '_get_'.$k;
  //NO check
  return $this->$m();
 }

 private function _get_a() { return 'a'; }

}

class Test extends Base {}

$x = new Test;
echo $x->a; 
//prints "a" both in php73 and php74

***So I expect that method_exists() in php74 should return (bool) true as in php73...because the method "EXISTS" is reached and executed***, or, for consinstency, php74 should throw a "PHP Fatal error:  Uncaught Error: Call to private method Test::_get_a()" when accessing _get_a() method. (But a huge amount of codebase is involved with no doubt)






Actual result:
--------------
php74 : PHP Fatal error:  Uncaught Exception: no-property-a in test.php
php73 : prints a
