Description:
------------
I tought to improve fetch_object such as follow code is useful:

mysqli_result::fetch_object ([ string $class_name = "stdClass" [[, string $field_name_prefix = ''], array $params ]] )

example code :

$result = $mysqli->query("select id,name from user limit 1");
$user = $result->fetch_object('stdClass','__');
var_dump($user);

output :

object stdClass {
  $__id = 1;
  $__name = 'someone';
}

-----------------------------------
in addition , i have a question :
 why call __constructor at the last in this method?

Can you provide some more use cases for this suggestion? Can you also sketch some specification detail for it? Also, sorry but I do not understand you question, perhaps try stackoverflow.

NOT stdClass. for example :
class UserEntity {
  function __construct(){
    $this->name = '';   // Default value from mysql schema
    $this->status = 1;  // default value from mysql schema
  }

  public $name;

  public $status;
}

////////////////////////////////////
Scene 1:
  $u = new UserEntity();
  $u->name = 'test';
  $u->status = 0;
  $userFactory->Save($u);

  this is correct.
////////////////////////////////////
Scene 2:
   $u = $result->fetch_object('UserEntity');
   var_dump($u);

  output :
    $u->name is '';
    $u->status is 1;

Thank you for this suggestion. However, I see absolutely no use for this kind of feature. You could simply alias the column names in SQL. 

You can start an RFC if you really require this feature.
