Bug description: singleton and inheritance
Description:
------------
Problem with create of object class then contruct is private. I use
singleton pattern and inheritance and I can create object (no error and
warning) if i didn't use inheritance was error (this behavior is ok).
Reproduce code:
---------------
<?php
class DB extends mysqli{
private static $instance;
private function __construct($hostname=DB_HOST, $username=DB_USER,
$password=DB_PASSWORD, $database=DB_DATABASE){
//parent::__construct($hostname, $username, $password,
$database);
}
public static function getInstance() {
if (!isset(self::$instance)) {
self::$instance = new DB();
}
return self::$instance;
}
}
$DB = new DB();
?>
Expected result:
----------------
Fatal error: Call to private DB::__construct()
Actual result:
--------------
Everything is ok. No error! No warning!
