Getting value from SOAP response in php - php

Question

I am getting a SOAP response for a SOAP call perfectly using SOAP ui but when I call the same in php, I am not able to traverse to the desired element(CreditId in this case), which I want.
The following is the SOAP response that I get using SOAP ui :
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
<soap-env:Header/>
<soap-env:Body>
<n0:getProjectCreditListResponse xmlns:n0="urn:sap-com:document:sap:soap:functions:mc-style">
<EUserGuid>33/XIcx+3/GxWABQVoJXWA==</EUserGuid>
<EtCurrCreditList>
<item>
<PhaseId/>
<CreditcategoryDescrption>Project Information Forms</CreditcategoryDescrption>
<CreditId>CSD1GSP1L-1000008140</CreditId>
</item>
<item>
<PhaseId/>
<CreditcategoryDescrption>Project Information Forms</CreditcategoryDescrption>
<CreditId>CSD1GSP2L-1000008140</CreditId>
</item>
</EtCurrCreditList>
<EtErrorLogInfo/>
</n0:getProjectCreditListResponse>
</soap-env:Body>
</soap-env:Envelope>
Now I have gone through the various similar questions on the site, where it is advised to do like this to get the desired element :
$client = new SoapClient('wsdl file path',array('trace'=>1,'exceptions'=>1);
$res = $client->getCreditFormDataXml(array(input arguments));
$xml = simplexml_load_string($res);
$xml->registerXPathNamespace('soap-env', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('n0', 'urn:sap-com:document:sap:soap:functions:mc-style');
foreach ($xml->xpath('//EtCurrCreditList//item//CreditId') as $item)
{
var_dump($item);
}
However I get an error stating that
Warning: simplexml_load_string() expects parameter 1 to be string
I have tried converting the $res variable to a string but it gives an error that
Object of class stdClass could not be converted to string
But if I do var_dump($res), I get output like this :
object(stdClass)[2]
public 'EUserGuid' => string 'ß×!Ì~ßñ±X�PV‚WX' (length=16)
public 'EtCurrCreditList' =>
object(stdClass)[3]
public 'EtErrorLogInfo' =>
object(stdClass)[4]
Why is the code not going to the sub nodes of the EtCurrCreditList so that I can then process it to get the desired value. - Solved
Final Output :
stdClass Object
(
[EUserGuid] => ß×!Ì~ßñ±XPV‚WX
[EtCurrCreditList] => stdClass Object
(
[item] => Array
(
[0] => stdClass Object
(
[PhaseId] =>
[PhaseDescription] =>
[CreditcategoryId] => CSD1GSL-1000008140
[CreditcategoryDescrption] => Project Information Forms
[CreditId] => CSD1GSP1L-1000008140
)
[1] => stdClass Object
(
[PhaseId] =>
[PhaseDescription] =>
[CreditcategoryId] => CSD1GSL-1000008140
[CreditcategoryDescrption] => Project Information Forms
[CreditId] => CSD1GSP2L-1000008140
)
[2] => stdClass Object
(
[PhaseId] =>
[PhaseDescription] =>
[CreditcategoryId] => CSD1GSL-1000008140
[CreditcategoryDescrption] => Project Information Forms
[CreditId] => CSD1GSP3L-1000008140
)
)
)
[EtErrorLogInfo] => stdClass Object

use echo"<pre>";print_r($res); you will be better able to understand how to traverse or show us the result.
$res=stdClass Object ( [EUserGuid] => ß×!Ì~ßñ±XPV‚WX [EtCurrCreditList] => stdClass Object ( ) [EtErrorLogInfo] => stdClass Object ( ) )
Now use
foreach($res->EUserGuid as $data)
{
//Your logic
}
same for EtCurrCreditList and EtErrorLogInfo and also nested loops if these object contain anything.
updating according to your new output.
you can iterate it like this
$res->EUserGuid=$something;
foreach($res->EtCurrCreditList->item as $eachItem)
{
$eachItem->PhaseId=$your_ wish;
$eachItem->PhaseDescription==$your_ wish;
$eachItem->CreditcategoryId==$your_ wish;
$eachItem->CreditcategoryDescrption==$your_ wish;
$eachItem->CreditId=$your_ wish;
}
and can ignore EtErrorLogInfo
