I'm using PHP's SoapClient to access a SOAP service. The provider of the service has told me that their WSDL is only for development and I shouldn't use it in production.
The SoapClient constructor expects the first argument to be the WSDL of the service, but also allows null, when working in non-WSDL mode.
I've been searching the RFCs and W3C for guidance, but haven't been able to find anything definitive on the use of WDSLs with SOAP.
Should someone who provides a SOAP service also provide a WSDL?
If someone who provides a SOAP service with a WSDL, is it correct to query that WSDL for each SOAP call?
Is it bad practice to provide a SOAP service without WSDL?
I wouldn't call it bad practice. It is a convention to provide a WSDL file at ?wsdl but you are not required to. There might be a reason why the provider doesn't want to expose the WSDL file, e.g. if it's a private web service.
The provider of the service has told me that their WSDL is only for development and I shouldn't use it in production.
So there is a WSDL file but it shouldn't be used? Now that sounds like a bad practice to me. IMO there should either be a valid WSDL file or no file at all. A file that doesn't reflect the actual web service will just cause confusion.
is it correct to query that WSDL for each SOAP call?
Yes the WSDL file is cached anyways and hence won't be queried every time.

for a customer I want to implement the OTA service in an interface to check availabilty and things like that.
I've downloaded the 2017 specifications from OpenTravel. But I lack some information. I want to realize it with PHP and SOAP and later connect it to Magento. But I can't find any url for the SOAP client to send those XMLs to.
I would greatly appreciate any help on this topic or maybe suggestions to do it in an easier way.
Greetings
Consuming OTA SOAP web services is tricky as PHP SoapClient class does not handle it properly.
First you should generate the PHP sdk from the WSDL corresponding to the availabilities you need to send requests to. You should give the PackageGenerator project from Github a try.
Nevertheless, as I said, the native PHP SoapClient class does not map the parameters to the XML request correctly. This is where you have to write your proper code to handle the mapping from the PHP objects to the XML request.
As I work regularly on these sorte of issues, I can help you further but only privately at contact#wsdltophp.com.
I´m trying to do an integration between my own PHP application, and other external software which is 'waiting for' (listening) SOAP messages. But the key question on my situation is that this software which is listening for SOAP messages only accepts RAW contents and has no method which could be called, or Wsdl to be used.
Yes I know... it´s quite strange because with SOAP you usually should send a method request with some parameters, but in this case the only that I have is a URL where I should send with SOAP message that should contain only an string (formatted in a special way which is not a problem), and then this server will return to my PHP application another SOAP message that will contain a string. And that´s all.
Seems that in my case I can not use a PHP SOAP library because I have no method (or function) to call; the only thing that I have is a URL and a string that I should pass like a parameter. I´ve been thinking of using PHP sockets to create a basic SOAP message to that 'strange soap server', but I have no clue about how to do it, or how I woule create with PHP a way to keep my application waiting for the answer comming from that external server.
Thank you so much for your help in advance.
You might be best of by just making the WSDL on your own. It isn't the most trivial thing to do, but it is well documented so you should be able to figure it out.
THere is no need to get the WSDL from the service you're sinding your requests to (it is rather better to have WSDL locally in some cases), so you just initialize the default SOAP client in PHP with that local WSDL, and off you go.
I'm setting up a SOAP service using the PHP SOAP server and client library.
I've coded some structured data types into my wsdl file with some heavy restrictions.
Do you know of functionality in the PHP SOAP library or of a 3rd party library which will check the actual parameters in the the server against the definitions of the WSDL file? Or do I have to code all my parameter checking explicitly into my SOAP server class, even though it is already coded in the WSDL?
In PHP 5.2 the SOAP server does not validate against the WSDL as described here http://bugs.php.net/bug.php?id=45966
I'm not sure about 5.3 though.
I've got a site running on php and I need my form to post data to an ASP.Net web service. All I have from the ASP.Net web service is a url ending in .svc and then I open up the url I get another link that I can click on which ends in .svc?wdsl
This is all pretty new to me so I'm not sure where to begin, any pointers?
Thanks
The ASP.NET site is exposing a WCF service, and the ?wsdl url you're seeing (pronounced wis-dul) is a XML file which describes all of the functionality provided by the service and the input/output parameters. See the Wikipedia article on Web Services Description Language for more info.
With the small amount of background info, you can find some examples about consuming a WCF service from PHP (the fact that it's a WCF service shouldn't make any difference btw, so any example of consuming a web service should work):
http://weblogs.asp.net/gunnarpeipman/archive/2007/09/17/using-wcf-services-with-php.aspx
http://spacebug.com/php-calling-wcf-part-2-html/
The .svc?wsdl link will give you the WSDL for the web service (which describes which methods are available and what their parameters are).
Once you have the WSDL, you can construct a SoapClient with it and call the methods.
It sounds like you've been given a .NET SOAP Web Service to consume.
Check out the PHP docs for consuming/working with SOAP Services:
PHP: SOAP - Manual (Paying close attention to SoapClient which is what you'll use to actually construct and call the service)
steven,
you'll need to do a refresher on wsdl and webservices under .net.
there are obviously lots of places to look online but certainly if you google: 'asp.net wcf wsdl webservice' you should get plenty of hits to help you along.

I have a WCF web service which allows both Basic HTTP and WS-HTTP clients, both over HTTPS using user name & password authentication. This is achieved with two bindings on the same service.
So, the service is at https://foo.com/Service.svc, the Basic HTTP (SOAP 1.1) endpoint is https://foo.com/Service.svc/Unp11, and the WS-HTTP (SOAP 1.2) endpoint is https://foo.com/Service.svc/Unp .
A client is trying to access this web service via PHP 5, using its built-in SOAP support, and is having trouble connecting to the service. He keeps getting an HTTP 400 (Bad Request) response, which tends to happen if the SOAP message is badly formed, or a SOAP 1.1 message is sent to a SOAP 1.2 endpoint (or vice versa).
I only know basic PHP so I'm having trouble helping him. I know you can create a client by doing
$client = new SoapClient('https://foo.com/Service.svc?wsdl');
but how do you specify the binding/endpoint? Are there any known issues achieving all this with PHP?
UPDATE
Ok, so I can use PHP to connect to the WCF service ok (specifying the SOAP version in the SoapClient constructor), and calling $client->__getFunctions() returns a correct list of all the web service operations.
When I try to call one using $client->__soapCall, the page just sits there loading for quite a while, and eventually returns the error "Error Fetching http headers". What exactly is this supposed to mean and how do I fix it? (Consuming the service from .Net client works perfectly.)
Just ran into this today, creating a WCF with multiple bindings for a PHP caller. Setting the location appears to allow for both the WSDL version of PHP's SoapClient and specifying a binding to use.
WCF config is (1 service with 2 bindings wsHttp and basicHttp), pretty straight-forward.
PHP code:
$client = new SoapClient("http://example.com/service.svc?wsdl");
$client->__setLocation("http://example.com/service.svc/basic");
$response = $client->MethodName(array( "paramName" => "paramValue" ... ));
We have a SOAP service which has several bindings. In C# when you add a service reference to a wsdl you get a class created for each one, but in PHP it seems you can't specify which binding you want to use - this has caused me problems when the bindings have conflicting type/method names. It does seem to generally work out OK though but I don't really know how it is dealing with it internally.
The other common problem I have had is that I always have to wrap up the parameters in loads of arrays or structs - sometimes you get a Bad Request back if the server is expecting a parameter and you haven't quite set it correctly. (see Having trouble getting my head around SOAP in PHP)
Not sure this is much help, just some thoughts. There are also some third-party Soap client implementations written in PHP that could be worth looking at, but they will be quite a lot slower.
