connecting to webservice Using PHP & Soap

Question

ok I'm trying to connect to a webservice which utilizes the OTA XML schema ("http://www.opentravel.org/OTA/2003/05/GetVehAvailRate")

this webservice is hosted at rentcentric.com, which is a hosted solution for taking reservations and bookings online, the system requires a username and password to connect & so far every attempt at connecting has resulted in a blank white page.

no error messages no PHP output,

Im still fairly new to using SOAP, (although I did have great success when using it on an estate agents site - which didnt require any authentication just a simple value to identify the company on that service)

I have read and tried nearly all the examples found on this site & others with no joy!

the request made to the service is outlined below, each request has a core set of arguments which are:

PickUpDateTime //date
ReturnDateTime //date
PickUpLocation.locationCode //string
ReturnLocation.locationCode //string
PromotionCod //string

the service url http://www2.rentcentric.com/Ota2007a/OTASrvc.asmx has all the methods available to us.

# GetVehAvailRate
# VehCancel
# VehLocSearch
# VehModify
# VehRes

Request -: GetVehAvailRate

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

      <POS>............

code example:

$soapClient = new SoapClient("http://www2.rentcentric.com/Ota2007a/OTASrvc.asmx?wsdl");

    // Prepare SoapHeader parameters
    $sh_param = array(
             'Username'=>'username',
             'Password'=>'password');
    $headers = new SoapHeader('http://www2.rentcentric.com/Ota2007a/', 'UserCredentials', $sh_param);

        // Prepare Soap Client
        $soapClient->__setSoapHeaders(array($headers));

Im just bangning my head against the wall trying to get something to return, All I need is pointed in the right direction...

Your sample code does not show you attempting to perform any actual calls to the service, or output the result. As well as the 'trace' option mentioned by user470714, you can also enable the 'exceptions' option so that "faults" returned by the server are thrown as Exceptions of class SoapFault. Obviously, you should also ensure you have your PHP error reporting configured correctly if you are see a blank output page. — IMSoP

Look at the documentation here:

http://www.php.net/manual/en/soapclient.soapclient.php

to see how to add the trace variable to your SoapClient constructor. Once you've done that you can use

SoapClient::__getLastRequestHeaders
SoapClient::__getLastRequest
SoapClient::__getLastResponse
SoapClient::__getLastResponseHeaders

As a means to, at the very least, get some feedback as to why your calls are failing.

You can try using another soap implementation and see if the problem persists. I suggest you Zend Soap
