php soapclient Array to string conversion - php

Question

I have an array a couple of levels deep in my SOAP request like below. When I run my SoapRequest I get Notice (8): Array to string conversion and my XML response does not convert the Array in RTrans to XML and I have no idea why. How I am creating the SOAP request and the XML version of it can be found below.
The Request:
$r['request'] = array(
'request' => array(
'user' => 'test',
'password' => 'test',
'RTrans' => array(
'Transactions' => array(
'Criteria' => array(
'Name' => 'Thomas'
)
)
)
)
);
try{
$response = $this->apiClient->DoQuery($r);
}
catch(Exception $e){
debug($e);
}
The XML Version
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="http://webServices/">
<SOAP-ENV:Body>
<ns1:DoNormalEnquiry>
<request>
<username>test</usernmae>
<password>test</password>
<RTrans>Array</RTrans>
</request>
</ns1:DoNormalEnquiry>
</SOAP-ENV:Body>

I think RTrans is defined as a String. Please have a look at the wsdl file.
Maybe thats the reason you got "Array" in the xml.
To send an array to your soapservice you could convert it to json.
json_encode( array('Transactions' => array('Criteria' => array('Name' => 'Thomas')));
or define a complex datatype.
Maybe SoapVar will help you.
