Issue with sending SOAP request, through soapclient, to service that expects CDATA - php

Question

I am trying to make a SOAP request to a service that expects CDATA as part of the request. I managed to do successfull calls using Insomnia with the following, either of the two works:
<ExecuteRequest xmlns="<url>">
<TAG1>
<![CDATA[
<TAG2>
<TAG3>TEXT1</TAG3>
<TAG4>TEXT2</TAG3>
<TAG5>TEXT3</TAG5>
</TAG2>
]]>
</TAG1>
</ExecuteRequest>
OR
<ExecuteRequest xmlns="<url>">
<TAG1>
<TAG2>
<TAG3>TEXT1</TAG3>
<TAG4>TEXT2</TAG4>
<TAG5>TEXT3</TAG5>
</TAG2>
</TAG1>
</ExecuteRequest>
But I've been having trouble translating the above to work with the php soapclient. For example using the following:
$soapclient = new SoapClient('url?wsdl', array('trace' => 1));
$xmlWriter = new \XMLWriter();
$xmlWriter->openMemory();
$xmlWriter->startElement('TAG1');
$xmlWriter->startElement('TAG2');
$xmlWriter->writeElement('TAG3','TEXT1');
$xmlWriter->writeElement('TAG4','TEXT2');
$xmlWriter->writeElement('TAG5','TEXT3');
$xmlWriter->endElement();
$xmlWriter->endElement();
$myXml = $xmlWriter->outputMemory(true);
$params = array(
new \SoapParam(new \SoapVar($myXml, XSD_ANYXML), 'param')
);
$response = $soapclient->__soapCall('ExecuteRequest',$params);
$lastrequest = $soapclient->__getLastRequest();
$soapclient->__getLastRequest() gives me this output which obviously isn't what I want, no CDATA:
<TAG1>
<TAG2>
<TAG3>TEXT1</TAG3>
<TAG4>TEXT2</TAG4>
<TAG5>TEXT3</TAG5>
</TAG2>
</TAG1>
If instead in the xmlwriter I use this to write the CDATA manually:
$xmlWriter->writeCdata('<TAG2>
<TAG3>TEXT1</TAG3>
<TAG4>TEXT2</TAG4>
<TAG5>TEXT3</TAG5>
</TAG2>');
Then for some weird reason $soapclient->__getLastRequest() returns the CDATA section commented out and I can't figure out why that is happening:
<TAG1>
<!--[CDATA[<TAG2-->
<TAG3>TEXT1</TAG3>
<TAG4>TEXT2</TAG4>
<TAG5>TEXT3</TAG5>
""]]>"
</TAG1>
Notice how TAG2's closing tag is lost as well.
EDIT
The same issue with the CDATA being commented out happens if I don't use the xml writter.
$wholeTag = new \SoapVar("<TAG1><![CDATA[{$text}]]></TAG1>", XSD_ANYXML);
$params = [
'param' => $wholeTag,
];
Any ideas? It's very likely that I'm going about this in the wrong way, so I'm open to any suggestion.

After wasting hours on this I ended up discarding using the soapclient altogether and solved it with Guzzle.
use GuzzleHttp\Client;
use GuzzleHttp\Exception\GuzzleException;
$xml = new \SimpleXMLElement("<put the whole xml body here, using the Webservice's SOAP 1.1 sample as a reference>");
$xmlstring = $xml->asXML();
$client = new Client();
$url = "< the **full** webservice url (used the Webservice's SOAP 1.1 sample as reference)>";
$action = "action url (used the Webservice's SOAP 1.1 sample as reference)";
try {
$response = $client->post($url,
['headers' =>
['SOAPAction' => $action,
'Content-Type' => 'text/xml; charset=utf-8',
'Host' => "<host url (used the Webservice's SOAP 1.1 sample as reference)>"
],
'body' => $xmlstring
]);
}
catch (GuzzleException $e)
{
return [ 'status' => $e->getResponse()->getStatusCode(), 'message' => $e->getResponse()->getReasonPhrase()];
}
if ($response->getStatusCode() === 200) {
// Success!
return $response->getBody();
}
