Sending Raw XML via PHP SoapClient request

Question

I am trying to simply send RAW xml to a webservice via PHP and SoapClient. The problem is when I encode my XML it changes the order of elements in the XML that is converted to an associative array.

// Initialize the Soap Client:
$this->_transactionServicesClient = new SoapClient($soapWSDLUrl);

How or what would be the best way to send the following XML as a string to my SoapClient?

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.micros.com/pos/les/TransactionServices">
    <SOAP-ENV:Body>
        <ns1:PostTransaction>
            <ns1:REQ>
                <ns1:RequestHeader>
                    <ns1:InterfaceVersion>3.0.7</ns1:InterfaceVersion>
                    <ns1:ClientName>TRANS_SERVICES</ns1:ClientName>

Update/Resolution: Here is the code I used to extend the SOAP Client and send my raw Soap Envelope

Here is how I extended SoapClient:

<?php
class MySoapClient extends SoapClient {

    function __construct($wsdl, $options) {
        parent::__construct($wsdl, $options);
        $this->server = new SoapServer($wsdl, $options);
    }
    public function __doRequest($request, $location, $action, $version) 
    { 
        $result = parent::__doRequest($request, $location, $action, $version); 
        return $result; 
    } 
    function __myDoRequest($array,$op) { 
        $request = $array;
        $location = 'http://xxxxx:xxxx/TransactionServices/TransactionServices6.asmx';
        $action = 'http://www.micros.com/pos/les/TransactionServices/'.$op;
        $version = '1';
        $result =$this->__doRequest($request, $location, $action, $version);
        return $result;
    } 
}

// To invoke my new custom method with my Soap Envelope already prepared.
$soapClient = new MySoapClient("http://xxxx:xxxx/TransactionServices/TransactionServices6.asmx?WSDL", array("trace" => 1)); 
$PostTransaction = $soapClient->__myDoRequest($orderRequest,$op); 
?>

For testing purposes, you can subclass SoapClient and override the __doRequest method - it receives the generated XML and you can pre-process it.

But better find what's going wrong with the XML encoding. You can use SoapVar and SoapParam instances to specify the exact way given object has to be represented. Those saved my life when namespaces had to be given
