Hallo. Ich möchte WhatsApp-Nachricht mit PHP senden. Ich führe diesen Code

<?php
require_once 'Chat-API-master/src/whatsprot.class.php';
$username = "6285648145xxx";
$nickname = "ardi";
$password = "password"; // The one we got registering the number
$debug = true;

// Create a instance of WhastPort.
$w = new WhatsProt($username, $nickname, $debug);

$w->connect(); // Connect to WhatsApp network
$w->loginWithPassword($password); // logging in with the password we got!

$target = '62811304xxxx'; // The number of the person you are sending the message
$message = 'Hi! :) this is a test message';

$w->sendMessage($target , $message);
?>

Aber ich habe diesen Code in meinem Browser erhalten

tx  <stream:features></stream:features>

tx  <auth user="6285648145xxx" mechanism="WAUTH-2"></auth>

rx  <from s.whatsapp.net=""></from>

rx  <stream:features></stream:features>
