Description:
------------
Hi,
in documentation here http://php.net/manual/en/mysqli-stmt.get-result.php is that method returns FALSE on failure. But this is not correct! This method is returning FALSE also for queries, which doesn't return values like INSERT, UPDATE, DELETE ...

There is also missing information how to check that mysqli_stmt::get_result() failed or not. Some example containing code like this would be helpful:

$stmt->execute();
$result = $stmt->get_result();
if ($stmt->errno) {
  // handle error here
}

I'm not the only one who is missing this information http://php.net/manual/en/mysqli-stmt.get-result.php#117718 

Expected result:
----------------
In documentation here http://php.net/manual/en/mysqli-stmt.get-result.php I see right information about returned values and example of code how can be checked if the mysqli_stmt::get_result() failed or not.
