PHP - Webservices: How To Display Response

I have an application which receives multiple requests at once and it advantageous to process them as a group.

I am thinking I should be doing something like the following, however, as I just came up with it on my own, would appreciate a critique.  Is this a common design pattern or should I be doing something differently?  Note that I have three questions asking specific questions in the below code (look for the comments with question marks).

Thanks
 

<?php
class Request
{
    private $response, $data;

    public function __construct(array $data)
    {
        $this->data=$data;
        return $this->response=new Response($this);
    }    

    public function getResponse():Response
    {
        return $this->response;
    }

    public function updateResponse($results):self
    {
        $this->response->setResults($results);
        return $this;
    }
}

<?php
class Response
{
    private $request, $results;

    public function __construct(Request $request)
    {
        //I don't really see the need for this.  Any need?
        $this->request=$request;
    }

    public function setResults($results):self
    {
        $this->results=$results;
        return $this;
    }

    public function getResults()
    {
        return $this->results;        
    }
}

<?php
class Container implements \Iterator
{
    private $position = 0;
    private $requests, $response;

    public function __construct(WorkerObject $worker, array $inputArray)
    {
        $this->requests=[];
        $this->responses=[];
        foreach($inputArray as $i =>$inputData) {
            $this->requests[$i]=new Request($inputData);
            $this->responses[]=$this->responses[$i]->getResponse();
        }

        //Should WorkerObject be responsible to execute Request::updateResponse() method? 
        $worker->process_requests(...$this->requests);

        //Or should I iterate over my requests upon completion and execute updateResponse() method? 
    }

    public function __construct() {
        $this->position = 0;
    }

    public function rewind() {
        $this->position = 0;
    }

    public function current() {
        return $this->responses[$this->position];
    }

    public function key() {
        //Will this work?
        return $this->requests[$this->position];
    }

    public function next() {
        ++$this->position;
    }

    public function valid() {
        return isset($this->responses[$this->position]);
    }
}

<?php
//...
$container=new Container(new WorkerObject, $inputArray);
foreach($container as $request => $response) {
    //...

I have this php file that processes Form field entries. Apparently I need to modify it, I'm told, to "validate the input and then send some response back":

<?php
if($_POST){
	$to = 'chrisj...@.....com';
	$subject = 'Thank you for your info';
	$name = $_POST['name'];
	$email = $_POST['email'];
	$message = $_POST['message'];
	$message1 = $_POST['message'];
	$headers = $name;
	$headers = 'from: info@.....com';
	$message1 .= "\r\n\r\nName: ".$_POST['name']." \r\n Email: ".$_POST['email']." ";
	$message = "Hello {$_POST['name']}, ~ Thank you for your input\r\n\r\n";
   		mail( $to, $subject, $message1, $headers );
   		mail( $email, $subject, $message, $headers );
		header('Location: https://....');
   exit;
}
?>

The corresponding js looks like this:

$.ajax({
  url: 'https://...../submit.php',
  method: 'post',
  data: {
    name: $('#name').val(),
    email: $('#email').val()
  },
  success: function (response) {
    console.log(response);
    if (response.success) {
      alert('Success');
    } else {
      alert('Error');
    }
  }
});

I look forward to any guidance with adding "validate the input and then send some response back".

Hi Guys,

I have this SOAP message to be parsed using SimpleXML:

<soap:envelope 
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:body>
    <isokresponse xmlns="http://tempuri.org/">
      <isokresult>1</isokresult>
    </isokresponse>
  </soap:body>
</soap:envelope>

Then I load the XML:

$xml = simplexml_load_string($result);

I assume I need to register namespace e.g.

$xml->registerXPathNamespace("soap","http://schemas.xmlsoap.org/soap/envelope/");

But what's next? How do I get the value of the element isokresult?

Thank you so much

Is there anything different between a response and a responder?  My thought is maybe a response is something that one application gives to another, and a responder is used only by a single application to create a response.

interface TrendInterface
{
    public function getResponse($blabla):TrendResponse;
    public function getResponder($blabla):TrendResponder;
}
