Description:
------------
Method mysqli::query supposed to have 2 parameters ($query [, $resultmode]), but ReflectionMethod::getParameters returns only first one.

Test script:
---------------
<?php

$class = new ReflectionClass('mysqli');

$method = $class->getMethod('query');

var_dump($method->getParameters());

Expected result:
----------------
array(2) { 
  [0]=> 
  object(ReflectionParameter)#3 (1) { 
    ["name"]=> string(5) "query" 
  }
  [1]=> 
  object(ReflectionParameter)#4 (1) { 
    ["name"]=> string(10) "resultmode" 
  } 
}

Actual result:
--------------
array(1) { 
  [0]=> object(ReflectionParameter)#3 (1) { 
    ["name"]=> string(5) "query" 
  } 
}
