Sending SMS messages via Twilio Rest API

I am looking at Twilio API right now for a project and I am surprised how easy is to handle voice and SMS messages. Here is an example, written by me:

ApiVersion = "2008-08-01";
	$this->AccountSid = "Axxxxxxxxxxxxxxxxxxxx"; //get your own after trial registration on Twilio.com
	$this->AuthToken = "axxxxxxxxxxxxxxxxxxxxx";
	$this->smsServer = new TwilioRestClient($this->AccountSid, $this->AuthToken);
}

function sendSMS($to, $from, $whattosend)
{

	$response = $this->smsServer->request("/$this->ApiVersion/Accounts/$this->AccountSid/SMS/Messages", 
			"POST", array(
			"To" => $to,
			"From" => $from,
			"Body" => $whattosend
		));
		if($response->IsError)
			echo "Error: {$response->ErrorMessage}";
		else
			echo "Done";



}


function __destruct()
{

	unset($this->ApiVersion);
	unset($this->AccountSid);
	unset($this->AuthToken); 
        
}

}


$s= new Twillio_SMS;
$s->sendSMS('4155992671','4155992671','this is a test');

?>
