PHP non blocking soap request

Question

After a user signs up on my website i need to send a soap request in a method that is not blocking to the user. If the soap server is running slow I don't want the end user to have to wait on it. Is there a way I can send the request and let my main PHP application continue to run without waiting from a response from the soap server? If not, is there a way to set a max timeout on the soap request, and handle functionality if the request is greater than a max timeout?

Edit: I would ideally like to handle this with a max timeout for the request. I have the following:

//ini_set('default_socket_timeout', 1);
      $streamOptions = array(
              'http'=>array(
                'timeout'=>0.01
            )
      );

      $streamContext = stream_context_create($streamOptions);

      $wsdl   = 'file://' . dirname(__FILE__) . '/Service.wsdl';

        try{
          if ( file_get_contents( $wsdl ) ) {

              $this->_soapClient = new SoapClient($wsdl,
                  array(
                      'soap_version' => SOAP_1_2,
                      'trace' => true,
                      'stream_context' => $streamContext
                  )
              );
              $auth = array('UserName' => $this->_username, 'Password' => $this->_password);
              $header = new SoapHeader(self::WEB_SERVICE_URL, "WSUser", $auth);
              $this->_soapClient->__setSoapHeaders(array($header));

          }//if
      }
      catch(Exception $e){
        echo "we couldnt connect". $e;
      }
$this->_soapClient->GetUser();

I set the timeout to 0.01 to try and force the connection to timeout, but the request still seems to fire off. What am I doing wrong here?

PHP (in combination with GTK, or HTML(5)) is exactly designed and ready for that. — Daniel W., Sep 27 '13 at 10:56

I have had the same issues and have implemented solution !

I have implemented

SoapClient::__doRequest();

To allow multiple soap calls using

curl_multi_exec();

Have a look at this asynchronous-soap

Four solutions:

Use AJAX to do the SOAP -> Simplest SOAP example
Use AJAX to call a second PHP file on your server which does the SOAP (best solution imo)
Put the SOAP request to the end of your PHP file(s) (not the deluxe solution)
Use pcntl_fork() and do everything in a second process (I deprecate that, it might not work with every server configuration)

Depending on the way you implement this, PHP has plenty of timeout configurations, for example socket_set_timeout(), or stream_set_timeout() (http://php.net/manual/en/function.stream-set-timeout.php)
