如何从PHP Web服务获取响应SOAP信封？

This is a simple question I think. I made a simple PHP web service with SoapServer and a simple client. I test this on soapUI and I get this:

I know is because of the var_dump() but I don't know how to make it respond a Response SOAP Envelope with the requested data.

PHP Server:

<?php

   if(!extension_loaded("soap")){

   dl("php_soap.dll");

}

   ini_set("soap.wsdl_cache_enabled","0");
   $wsdl='InterconexionTest.wsdl';
   function ejecutarTransaccionTest($input){
    return (object)array('ejecutarTransaccionTestReturn'   => '0210B22080010E80800000000000000000183550000000000000000221150711577994022106520900                  000056    0000023041902000002     111111     REC     784 0117507902             MARINA DE GUERRA DEL01000000000682001000003          3000          REC604S                                                                                 00103FFFFFRECT001-0062563    17507902        200204220000000000000000021277RECT001-0076270    17507902        200205220000000000000000022225RECT001-0097858    17507902        200206220000000000000000008796                                                                                                                                                                                                                ');
   }
   $server = new SoapServer($wsdl);
   $server->AddFunction("ejecutarTransaccionTest");
   $server->handle();
?>

PHP Client:

<?php
try{

    $wsdl='InterconexionTest.wsdl';
    $sClient = new SoapClient($wsdl);
    $response = $sClient->ejecutarTransaccionTest("Input");
    var_dump($response);

} catch(SoapFault $e){
    var_dump($e);
}
?>

Can someone tell me how?

First, my apologies for not have being able to answer this myself before, but I've been searching for hours and missed this easily.

Just to add ?wsdl at the endpoint solves this issue, and to use the servidor.php instead of cliente (servidor = server in English. The SoapServer)

Thanks beforehand for the attention and understanding.
