When you receive the soapfault message: "looks like we got no XML document" it might be that you're talking to a server that supports MTOM (http://www.w3.org/TR/soap12-mtom/).

MTOM is, as of yet (5.3.6), not supported by the SoapClient.

I needed to perform SOAP actions and get information from a Windows ASP.NET server and encountered many errors along the way.
At first I had it solved with NUSOAP, and sending my own XMLs with it, but then when I needed to use SSL it failed again.

So I went back to a regular SoapClient (as opposed to nusoap_client) and now I am using the WSDL defined functions ($client->function($params)).

The ASP.NET server I'm consuming is quite strange, the WSDL definition does not define the parameters I need to send, they only define one parameter and they expect me to send another XML within that.

So here's my solution, in case it helps anyone:
$params['trace'] = true;
$client = new soapclient('https://www.example.com/WebService.asmx?WSDL', $params);
$msg['AccountData']['any'] = "<somexml></somexml><otherxml></otherxml>";
$client->Function($msg);
$resulta = xml2array($client->__getLastResponse());

“SOAP-ERROR: Parsing WSDL: Couldn’t find in ‘PATH/TO/YOUR/WSDL’”

This error occurs because some versions of PHP SOAP client  do not send the user name and password that you pass as the options input parameter of the SoapClient constructor  . Yu need to pass the credentials in the web service URL like this:
$soapClient =new SoapClient(“http://user:password@example.com/blahblah.wsdl”);

It can be a nightmare trying to get all the details for a SOAP implementation into a handy class for PHP. If you are ever in this situation, thought I would let you know about a site that generates a PHP class ready to use with a SOAP server using native SoapClient in PHP 5. Its free to use, and can be found at www.apigenerator.com.

I was trying to figure out for days and days to make SOAP server return an associative array and NOT an object ....

To get an array (not object) in the SOAP response, just serialize the array before returning it to the clent..

hope it helps...
Thanks.....

Here is an example of a php client talking to a asmx server:

<?php

        $soapClient
= new SoapClient("https://soapserver.example.com/blahblah.asmx?wsdl");
   
       
// Prepare SoapHeader parameters
       
$sh_param = array(
                   
'Username'    =>    'username',
                   
'Password'    =>    'password');
       
$headers = new SoapHeader('http://soapserver.example.com/webservices', 'UserCredentials', $sh_param);
   
       
// Prepare Soap Client
       
$soapClient->__setSoapHeaders(array($headers));
   
       
// Setup the RemoteFunction parameters
       
$ap_param = array(
                   
'amount'     =>    $irow['total_price']);
                   
       
// Call RemoteFunction ()
       
$error = 0;
        try {
           
$info = $soapClient->__call("RemoteFunction", array($ap_param));
        } catch (
SoapFault $fault) {
           
$error = 1;
            print(
"
            alert('Sorry, blah returned the following ERROR: "
.$fault->faultcode."-".$fault->faultstring.". We will now take you back to our home page.');
            window.location = 'main.php';
            "
);
        }
       
        if (
$error == 0) {       
           
$auth_num = $info->RemoteFunctionResult;
           
            if (
$auth_num < 0) {
                ....

               
// Setup the OtherRemoteFunction() parameters
               
$at_param = array(
                           
'amount'        => $irow['total_price'],
                           
'description'    => $description);
           
               
// Call OtherRemoteFunction()
               
$trans = $soapClient->__call("OtherRemoteFunction", array($at_param));
               
$trans_result = $trans->OtherRemoteFunctionResult;
            ....
                } else {
                   
// Record the transaction error in the database
               
                // Kill the link to Soap
               
unset($soapClient);
            }
        }
    }   
}
   
?>

If anyone is trying to use this for accessing Sabre's web services, it won't work. Sabre checks the request header "Content-Type" to see if it is "text/xml" . If it is not text/xml then it sends an error back.

You will need to create a socket connection and use that to send the request over.

Juste a note to avoid wasting time on php-soap protocol and format support.

Until php 5.2.9 (at least) the soap extension is only capable of understanding wsdl 1.0 and 1.1 format.

The wsdl 2.0, a W3C recommendation since june 2007, ISN'T supported in php soap extension.
(the soap/php_sdl.c source code don't handle wsdl2.0 format)

The wsdl 2.0 is juste the 1.2 version renamed because it has substantial differences from WSDL 1.1.

The differences between the two format may not be invisible if you don't care a lot.

The wsdl 1.0 format structure (see http://www.w3.org/TR/wsdl) :
<definitions ...>
    <types ...>
    </types>
    <message ...>
        <part ...>
    </message>
    <portType ...>
        <operation ...>
            <input ... />
            <output ... />
            <fault ... />
        </operation>
    </portType>
    <binding ...>
        <operation ...>
            <input ... />
            <output ... />
            <fault ... />
        </operation>
    </binding>
    <service ...>
        <port ...>
    </service>
</definitions>

And the wsdl 2.0 format structure (see http://www.w3.org/TR/wsdl20/) :
<description ...>
    <types ...>
    </types>
    <interface ...>
        <fault ... />
        <operation ...>
            <input ... />
            <output ... />
            <fault ... />
        </operation>
    </interface>
    <binding ...>
        <fault ... />
        <operation ...>
            <input ... />
            <output ... />
            <fault ... />
        </operation>
    </binding>
    <service ...>
        <endpoint ...>
    </service>
</description>

The typical error message if you provide a wsdl 2.0 format file :
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't find <definitions> in 'wsdl/example.wsdl' in /path/client.php on line 9

Named parameters are actually super easy once you know how to do it. No need to bother with SoapParam or SoapVar for the most part.

The code:
<?php
$ws
->getAsset(array(
 
'assetId' => 5967
));
?>

Generates the following SOAP body: (formatted for readability)
<SOAP-ENV:Body>
  <ns1:getAsset>
    <assetId>5967</assetId>
  </ns1:getAsset>
</SOAP-ENV:Body>

To save yourself a couple days of heart-ache, if you are trying to access a Windows server using SOAP and it seems as though the parameters are not being passed through to the Windows server, it is because of a bug in PHP. Because if you examine the SOAP packets going out (with Wireshark), you'll see that the parameter names are there in the <soap:Body>, but they have no values.

So instead, you should use the NuSOAP class and it will work perfectly: http://sourceforge.net/projects/nusoap/

I hope this helps and saves you pulling out your hair over this issue. :)

If you've been trying to send null to a service that considers empty property tags as empty strings rather than null, here's an extending class that fixes this using xsi:nil:

<?php
class XSoapClient extends SoapClient
{
    const
XSI_NS = "http://www.w3.org/2001/XMLSchema-instance";
    const
_NULL_ = "xxx_replacedduetobrokephpsoapclient_xxx";

    protected
$mustParseNulls = false;

    public function
__doRequest($request, $location, $action, $version, $one_way = null)
    {
        if(
$this->mustParseNulls)
        {
           
$this->mustParseNulls = false;
           
$request = preg_replace('/<ns1:(\w+)>'.self::_NULL_.'<\/ns1:\\1>/',
                       
'<ns1:$1 xsi:nil="true"/>',
                       
$request, -1, &$count);

            if (
$count > 0)
            {
               
$request = preg_replace('/(<SOAP-ENV:Envelope )/',
                   
'\\1 xmlns:xsi="'.self::XSI_NS.'" ',
                   
$request);
            }
        }
        return
parent::__doRequest($request, $location, $action, $version, $one_way);
    }

    public function
__call($method, $params)
    {
        foreach(
$params as $k => $v)
        {
            if(
$v === null)
            {
               
$this->mustParseNulls = true;
               
$params[$k] = self::_NULL_;
            }
        }
        return
parent::__call($method, $params);
    }
}
?>

If you are having an issue where SOAP cannot find the functions that are actually there if you view the wsdl file, it's because PHP is caching the wsdl file (for a day at a time). To turn this off, have this line on every script that uses SOAP: ini_set("soap.wsdl_cache_enabled", "0"); to disable the caching feature.

The problem with the PHP WebService Client

We've a JAVA WebService Server which could have attached documents. When the PHP Client send the dates, the Server take it correctly, but when
the server return it to the PHP Client, the client reply always that is not a XML valid document.

The problem could be than the JAVA Server adds (to this type of XML binary files)  the documentType head: xml+xop and the clean doesn't understand
this head as a XML document.

There is some possibility to solve this problem in the PHP Client without doing changes in the JAVA Server?

SoapFault exception: [SOAP-ENV:Client] looks like we got no XML document

This error can have to reasons:
1: Your server script has some hidden output like spaces before or afher <?php ... ?> or echoing some text
2: You have a bug in your server script;
    resulting in a error message output

Test your server script by calling it direct  from the browser.
The result should be a clean output like :

−<SOAP-ENV:Envelope>
−<SOAP-ENV:Body>
−<SOAP-ENV:Fault>
  <faultcode>SOAP-ENV:Server</faultcode>
  <faultstring>Bad Request. Can't find HTTP_RAW_POST_DATA</faultstring>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This tell's you there was a request but without data; This is OK
Now if you get the error when calling with your soap client;
remember that your server now will call other functions in the server.php script because it now has some data to process

PROBLEM (with SOAP extension under PHP5) of transferring object, that contains objects or array of objects. Nested object would not transfer.

SOLUTION:
This class was developed by trial and error by me. So this 23 lines of code for most developers writing under PHP5 solves fate of using SOAP extension.

<?php
/*
According to specific of organization process of SOAP class in PHP5, we must wrap up complex objects in SoapVar class. Otherwise objects would not be encoded properly and could not be loaded on remote SOAP handler.

Function "getAsSoap" call for encoding object for transmission. After encoding it can be properly transmitted.
*/
abstract class SOAPable {
    public function
getAsSOAP() {
        foreach(
$this as $key=>&$value) {
           
$this->prepareSOAPrecursive($this->$key);
        }
        return
$this;
    }

    private function
prepareSOAPrecursive(&$element) {
        if(
is_array($element)) {
            foreach(
$element as $key=>&$val) {
               
$this->prepareSOAPrecursive($val);
            }
           
$element=new SoapVar($element,SOAP_ENC_ARRAY);
        }elseif(
is_object($element)) {
            if(
$element instanceof SOAPable) {
               
$element->getAsSOAP();
            }
           
$element=new SoapVar($element,SOAP_ENC_OBJECT);
        }
    }
}

// ------------------------------------------
//  ABSTRACT EXAMPLE
// ------------------------------------------

class PersonList extends SOAPable {
  protected
$ArrayOfPerson; // variable MUST be protected or public!
}

class
Person extends SOAPable {
  
//any data
}

$client=new SoapClient("test.wsdl", array( 'soap_version'=>SOAP_1_2, 'trace'=>1, 'classmap' => array('Person' => "Person", 'PersonList' => "PersonList")  ));

$PersonList=new PersonList;

// some actions

$PersonList->getAsSOAP();

$client->someMethod($PersonList);

?>

So every class, which will transfer via SOAP, must be extends from class SOAPable. 
As you can see, in code above, function prepareSOAPrecursive search another nested objects in parent object or in arrays, and if does it, tries call function getAsSOAP() for preparation of nested objects, after that simply wrap up via SoapVar class.

So in code before transmitting simply call $obj->getAsSOAP()
