Subject: Re: [PHP-DEV] [RFC] Anonymous Classes
From: mails@thomasbley.de ("Thomas Bley")

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.

Regards
Thomas
