PHP SoapClient not getting substructures - php

Question

I'm trying to get the response of A SOAP Service, but I can't get the subcollections data.
When I call the ws method using a soap client software I get the next response:
<WSGLMSuit.METHODNAME xmlns="http://tempuri.org/">
<Sdtpolizadetalle>

<DscEmpresa>TEST</DscEmpresa>

So, I made a function in PHP with SoapClient class to make same request and get the result parsed as JSON but it doesn't giving me the "Suplementos" collection and its data.
{
"Sdtpolizadetalle": {
"Empresa": 1,
"DscEmpresa": "TEST",
"Rama": 22,
"DscRama": "COMBINADO FAMILIAR",
"Poliza": 129031,
"DscRiesgo": "",
"InicioVigencia": "2019-03-18",
"FinVigencia": "2019-09-18",
"Productor": 3311,
"NombreProductor": "TEST",
"Tomador": {
"CodTomador": 336028,
"NombreTomador": "TEST",
"Domicilio": "SAAVEDRA 1174 Dpto. 0",
"Localidad": "TRES ARROYOS",
"CodigoPostal": "7500"
},
"DscMoneda": "PESOS",
"CantidadCuotas": 3,
"Suplementos": {} // <--- HERE IS THE ISSUE
},
"Sesionexpirada": false
}
The PHP function is:
$wsdl = "http://wsdlservice.org?wsdl";
$params = $request->getParsedBody();
$options = array(
'soap_version' => SOAP_1_2,
'style' => SOAP_DOCUMENT,
'use' => SOAP_LITERAL,
'exceptions' => true,
'trace' => 1,
'cache_wsdl' => WSDL_CACHE_NONE,
'encoding' => 'UTF-8'
);
$soap = new SoapClient($wsdl, $options);
$clientRes = $soap->METHODNAME($params);
return json_encode($clientRes, JSON_PRETTY_PRINT);

Finally I got a solution. I found a function for parsing XML string to Array. So what I do is get the response as XML, save it into a file and parse it with that function. Code better than words:
function xmlToArray($xml, $options = array())
{
$defaults = array(
'namespaceSeparator' => ':',
'attributePrefix' => '#',
'alwaysArray' => array(),
'autoArray' => true,
'textContent' => '$',
'autoText' => true,
'keySearch' => false,
'keyReplace' => false
);
$options = array_merge($defaults, $options);
$namespaces = $xml->getDocNamespaces();
$namespaces[''] = null;
$attributesArray = array();
foreach ($namespaces as $prefix => $namespace) {
foreach ($xml->attributes($namespace) as $attributeName => $attribute) {
if ($options['keySearch']) $attributeName =
str_replace($options['keySearch'], $options['keyReplace'], $attributeName);
$attributeKey = $options['attributePrefix']
. ($prefix ? $prefix . $options['namespaceSeparator'] : '')
. $attributeName;
$attributesArray[$attributeKey] = (string)$attribute;
}
}
$tagsArray = array();
foreach ($namespaces as $prefix => $namespace) {
foreach ($xml->children($namespace) as $childXml) {
$childArray = xmlToArray($childXml, $options);
list($childTagName, $childProperties) = each($childArray);
if ($options['keySearch'])
$childTagName = str_replace($options['keySearch'], $options['keyReplace'], $childTagName);
if ($prefix)
$childTagName = $prefix . $options['namespaceSeparator'] . $childTagName;
if (!isset($tagsArray[$childTagName])) {
$tagsArray[$childTagName] =
in_array($childTagName, $options['alwaysArray']) || !$options['autoArray']
? array($childProperties)
: $childProperties;
} elseif (
is_array($tagsArray[$childTagName]) && array_keys($tagsArray[$childTagName])
=== range(0, count($tagsArray[$childTagName]) - 1)
) {
$tagsArray[$childTagName][] = $childProperties;
} else {
$tagsArray[$childTagName] = array($tagsArray[$childTagName], $childProperties);
}
}
}
$textContentArray = array();
$plainText = trim((string)$xml);
if ($plainText !== '') $textContentArray[$options['textContent']] = $plainText;
$propertiesArray = !$options['autoText'] || $attributesArray || $tagsArray || ($plainText === '')
? array_merge($attributesArray, $tagsArray, $textContentArray) : $plainText;
return array(
$xml->getName() => $propertiesArray
);
}
$params = array('key' => 'value') // params needed to make the request
$options = array(
'trace' => 1,
'exceptions' => true
);
try {
$soap = new SoapClient($url, $options);
$soap->method($params); // replace method name
$xmlResponse = $soap->__getLastResponse();
} catch (Exception $e) {
die(
json_encode(
[
'error' => 'Cannot request to WS. ' . $e->getMessage()
]
)
);
// save the response into an xml file for parse
// it and return its content as json
if (file_put_contents('response.xml', $xmlResponse)) {
$xmlNode = simplexml_load_file($this->tempPath);
$arrayData = xmlToArray($xmlNode);
unlink('response.xml');
return json_encode($arrayData, JSON_PRETTY_PRINT);
} else {
return json_encode(['error' => 'Error saving the response into file.']);
}
