Re: [RFC] Anonymous Classes

here is an example for opening a mysqli connection only when the first query is executed: $c = new class extends mysqli { public function query($query, $resultmode = MYSQLI_STORE_RESULT) { if (empty($this->host_info)) parent::real_connect('127.0.0.1', 'user', 'pwd', 'db'); return parent::query($query, $resultmode); } } // do sth for some time $->query('...'); // triggers real_connect $->query('...'); // connection is already established I haven't tested this, so I'm only intending to present the idea.
