使用yii2发送SMS消息

Question

我从yii2开始。我想用yii2发送短信。有人可以帮忙吗？

我写了这段代码，但看不到结果

$phone = array($_POST["phone"]);
    $message = array($rand); 
    $client = new SoapClient("http://parsasms.com/webservice/v2.asmx?WSDL");
    $params = array(
        'username' => 'demo',
        'password' => 'demo',
        'senderNumbers' => array("30005006002651"),
        'recipientNumbers'=> $phone,
        'messageBodies' => $message
    )
);
$results = $client->SendSMS( $params );
