How to add attributes to soapVars - php

Question

I'd like to create soapVars with attributes like this:
<tag attr="xxx">yyy</tag>
Is this possible with the SoapVar constructor, but without using XSD_ANYXML and raw xml strings?

Answer 1

The best way to do it is:
<?php
$tag['_'] = 'yyy';
$tag['attr'] = 'xxx';
$tagVar = new SoapVar($tag, SOAP_ENC_OBJECT);
?>
the result would be:
<tag attr="xxx">yyy</tag>

Answer 2

After spending many hours searching for a solution, I only found this workaround. Works in my case.
/**
* A SoapClient derived class that sets the namespace correctly in the input parameters
*/
class SoapClientNS extends SoapClient {
// return xml request
function __doRequest($request, $location, $action, $version, $one_way = NULL) {
//Replace each <Typename> with <ns1:Typename> or
$request = str_replace('RequestBase', 'ns1:RequestBase', $request);
return parent::__doRequest($request, $location, $action, $version, $one_way);
}
}
$client = new SoapClientNS($wsdlURL);
$client->getAllBooks(array('RequestBase' => array('code' => 'AAAA', 'password' => '234234fdf')));
The request XML was something like this:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.travco.co.uk/trlink/xsd/country/request">
<env:Body>
<ns1:getAllBooks>
<RequestBase code="AAAA" password="234234fdf"/>
</ns1:getAllBooks>
</env:Body>
</env:Envelope>

pcmind's answer did not work for me, and also not if you try it in PhpFiddle.
I stumbled on this article, which basically creates xml with XMLWriter:

This totally works for my case.
