PHP — how to connect to Mongo on demand (delay)?

class lazyLoad_mongo { private $loaded = false; private $mongo; public function init() { $this->mongo = new Mongo(MONGO_SERVER, array ("connect" => false)); $this->loaded = true; } public function __call($name, array $arguments) { if (!$this->loaded) { $this->init(); } return call_user_func_array(array($this->mongo, $name), $arguments); } public function __callStatic($name, array $arguments) { $this->__call($name, $arguments); } public function __get($name) { if (!$this->loaded) { $this->init(); } return $this->mongo->$name; } public function __set($name, $value) { if (!$this->loaded) { $this->init(); } return $this->mongo->$name = $value; } public function __isset($name) { if (!$this->loaded) { $this->init(); } return isset($this->mongo->$name); } public function __unset($name) { if (!$this->loaded) { $this->init(); } return unset($this->mongo->$name); } } 

function makeRequest() { if (!$this->isConnected()) { $this->connect(); } parent::makeQuery(); }
