i trying create simple test web service in php using zend framework 2.2.1. using xampp v1.8.2-0. version of php installed 5.4.16. have followed skeleton application tutorial @ http://framework.zend.com/manual/2.0/en/user-guide/skeleton-application.html point have functioning controller.

the wsdl path testws.localhost/album/wsdl or testws.localhost/album?wsdl service located @ testws.localhost/album. 127.0.0.1 in place of testws.localhost makes no difference.

visiting wsdl url returns me appears valid wsdl file, xmlspy loads/validates it. visiting service in browser results in error response above, not give detail why cannot load wsdl.

saving generated wsdl output file , using path that, generating text in php within soap request method generate same error, couldnt load 'x' : failed load external entity 'x'. wsdl file can read in application directory , echoed out.

i have spent multiple days trying resolve , looked @ plenty of similar questions here , on web of them either magically resolve or have no accepted answer, , nothing suggested worked me. code included below, if there other information required let me know, relatively inexperienced zend framework / php / xampp , has me stopped completely.

albumcontroller.php

<?php namespace album\controller;  require_once 'soaptest.php';  use zend\mvc\controller\abstractactioncontroller; use zend\view\model\viewmodel; use zend\soap\server; use zend\soap\autodiscover;  class albumcontroller extends abstractactioncontroller {     private $_wsdl_uri = "http://testws.localhost/album/wsdl";     private $_uri = "http://testws.localhost/album";      public function indexaction()     {             if(isset($_get['wsdl']))          {             $this->handlewsdl();         }          else          {             $this->handlesoap();         }         return $this->getresponse();     }      public function wsdlaction()     {            $this->handlewsdl();         return $this->getresponse();     }      private function handlewsdl() {         $autodiscover = new autodiscover();         $autodiscover->seturi('soaptest');         $autodiscover->setclass($this->_uri);         $autodiscover->handle();     }      private function handlesoap() {         try          {             $server = new server($this->_wsdl_uri);             $server->setclass('soaptest');             $server->handle();                   }          catch (exception $e)          {               $e->faultstring->dump("error.wsdl");          }       } } 

soaptest.php

<?php class soaptest {     /**      * method returns string      *       * @param string $value      * @return string      */     public function hello($value) {         return "hi";     } } 

in httpd-vhosts.conf

i think problem in controller, first $_uri must

$_uri = "http://testws.localhost/album"; 

(i.e. http schema).

second passing wrong argument autodiscover, first argument of autodiscover not url, try replacing handlewsdl method this:

private function handlewsdl() {     $autodiscover = new autodiscover();     $autodiscover->setclass('soaptest')                  ->seturi($this->_uri);     $autodiscover->handle(); }
