Generating XML SOAP message in PHP - php

Question

I need help generating XML SOAP message in PHP. I'm using BeSimpleSoap extension. I've tried many different ways to generate SOAP message.
Message should look like this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://apis-it.hr/umu/2015/types/kp" xmlns:gsb="http://apis-it.hr/umu/2013/types/gsb">
<soapenv:Header/>
<soapenv:Body>
<gsb:SendMessageRequest>
<gsb:GsbEnvelope>
<gsb:MessageHeader>
<gsb:SenderId>1</gsb:SenderId>
<gsb:ServiceId>126</gsb:ServiceId>
<gsb:MessageId>c4413331-1cff-11e2-f516-242d656ac4b3</gsb:MessageId>
<gsb:SenderTimeStamp>2015-05-31T12:00:00</gsb:SenderTimeStamp>
</gsb:MessageHeader>
<gsb:Content>
<gsb:MimeType>aaa</gsb:MimeType>
<gsb:Data encoding="EMBEDDED">
<tns:Upit>
<tns:IdPosiljatelja>1</tns:IdPosiljatelja>
<tns:TipPoruke>1</tns:TipPoruke>
<tns:IdUpita>732262f1-063f-11e2-892e-0812200c9f68</tns:IdUpita>
<tns:DatumVrijemeUpita>2015-03-26T15:33:29.371+01:00</tns:DatumVrijemeUpita>
</tns:Upit>
</gsb:Data>
</gsb:Content>
</gsb:GsbEnvelope>
</gsb:SendMessageRequest>
</soapenv:Body>
</soapenv:Envelope>
I have tried to generat XML with this:
$encodded = new SoapVar("<tns:Upit>
<tns:IdPosiljatelja>196</tns:IdPosiljatelja>
<tns:TipPoruke>$TipPoruke</tns:TipPoruke>
<tns:IdUpita>$UUID</tns:IdUpita>
<tns:DatumVrijemeUpita>$date_time</tns:DatumVrijemeUpita>
</tns:Upit>", XSD_ANYXML);
$par_envelope=array( "GsbEnvelope" =>
array( "MessageHeader" =>
array("SenderId" => "24",
"ServiceId" => "$ServiceId",
"MessageId" => $UUID,
"SenderTimeStamp" => $date_time),
"Content" => array("MimeType" =>"application/xml","Data" =>array("any"=>$encodded,"encoding"=>"EMBEDDED"))));
$par_WSDL=array("trace"=>TRUE,
"exceptions"=>TRUE,
'location'=>$SERVICE_TEST,
"local_cert" =>$SOAP_cert,
'uri'=>$NAMESPACE_URI,
"passphrase"=>$cert_password,
"connection_timeout" => 60);
$client = new BeSimple\SoapClientSoapClient("GSBService.wsdl",$par_WSDL);
$result=$client->sendMessage($par_envelope);
But that only generated part of a XML message that looks like:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://apis-it.hr/umu/2013/types/gsb">
<SOAP-ENV:Body>
<ns1:SendMessageRequest>
<ns1:GsbEnvelope>
<ns1:MessageHeader>
<ns1:SenderId>1</ns1:SenderId>
<ns1:ServiceId>1</ns1:ServiceId>
<ns1:MessageId>34578b73-988a-4727-bee4-a287218cc0a1</ns1:MessageId>
<ns1:SenderTimeStamp>2015-10-01T09:07:25+02:00</ns1:SenderTimeStamp>
</ns1:MessageHeader>
<ns1:Content>
<ns1:MimeType>application/xml</ns1:MimeType>
<ns1:Data/>
</ns1:Content>
</ns1:GsbEnvelope>
</ns1:SendMessageRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
EDIT Here you can see WSDL and XSD files.

It seems that the library adds its own namespace prefixes. This is not a problem. In XML the following 3 examples have the same meaning:
<ns1:SendMessageRequest xmlns:ns1="http://apis-it.hr/umu/2013/types/gsb">
<gsb:SendMessageRequest xmlns:gsb="http://apis-it.hr/umu/2013/types/gsb">
<SendMessageRequest xmlns="http://apis-it.hr/umu/2013/types/gsb">
The XML parser will resolve all 3 to an element node with the local name SendMessageRequest in the namespace http://apis-it.hr/umu/2013/types/gsb.
So the changed prefix is not a problem. The library can do this to generate/optimize the output.
But, your XML Soap variable is not valid XML. You did not add the namespace definition. If an element has a prefix you will need a namespace definition for this prefix on the element node or one of its ancestors.
$encoded = new SoapVar(
"<tns:Upit xmlns:tns='http://apis-it.hr/umu/2015/types/kp'>
<tns:IdPosiljatelja>196</tns:IdPosiljatelja>
<tns:TipPoruke>$TipPoruke</tns:TipPoruke>
<tns:IdUpita>$UUID</tns:IdUpita>
<tns:DatumVrijemeUpita>$date_time</tns:DatumVrijemeUpita>
</tns:Upit>",
XSD_ANYXML
);

I would advise you to only use array or objects to generate the request that is simply pass as parameter to your SoapClient. And not mix xml strings and Objects.
For example, if ou use a WSDL to php generator, you'll only deal with PHP objects and the XML request will be generated natively by the SoapClient in order to send it to the SOAP Server.
If I can advise you some good WSDL to php generator:
wsdltophp.com
PackageGenerator
