Correct XML request with Curl: getting blank XML response - php

Question

I was trying to hit XML request from PHP SOAP Client according to the following provided SOAP API documentation.
WSDL Schema
Refer to the following URL.
http://[SERVER_IP]/PowerSuite/PSXMLSearch.asmx?wsdl
4 Input/Output
4.1 Search Supplier Code and Name (PSXMLSearchSupplier)
Input : PSXML_SEARCH_SUPP
Output : PSXML_SEARCH_SUPP_Response
6 Field definition
6.1 PSXML_SEARCH_SUPP - The main entry point and the authentication information.
MSGID
USERID
PASSWORD
OPTION
SUPPNO
But when i run with SOAP client it gives me a following error
Object reference not set to an instance of an object
So after long research on internet, i decided to send XML request via CURL, i have created following Schema for XML request and send it via CURL request
$soapUrl = "https://[MY_SERVER_DOMAIN]/PowerSuite/PSXMLSearch.asmx"; // asmx URL of WSDL
// xml post structure
$xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<PSXML_SEARCH_SUPP xmlns="https://[MY_SERVER_DOMAIN]/PowerSuite/PSXMLSearch.asmx">
<MSGID>TRAVEK_E1</MSGID>
<USERID>GCOT</USERID>
<PASSWORD>CKHOSKIS6</PASSWORD>
<OPTION>LIKE</OPTION>
<SUPPNO>RK0048</SUPPNO>
</PSXML_SEARCH_SUPP>
</soap:Body>
</soap:Envelope>';
$headers = array(
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: \"https://[MY_SERVER_DOMAIN]/PowerSuite\"",
"Content-length: ".strlen($xml_post_string),
);
$url = $soapUrl;
// PHP cURL for https connection with auth
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "GCONNECT:Connect#786");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// converting
$response = curl_exec($ch);
curl_close($ch);
// converting
$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);
// convertingc to XML
$parser = simplexml_load_string($response2);
// user $parser to get your data out of XML response and to display it.
echo "<pre>";
print_r($parser);
echo "</pre>";
die();
But even after that i only get empty XML response as can see below
SimpleXMLElement Object

Please guide am i sending a correct XML schema, or their needs to be some thing amend into it?

I checked with RapidAPI, it shows the correct response, i have shown the request in the image below:
In FORM
https://gcdnb.pbrd.co/images/a9NdABt6rXQl.png
In XML
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xh="http://www.xmlhk.com/">
<soapenv:Header/>
<soapenv:Body>
<xh:PSXMLSearchSupplier>
<!--Optional:-->
<xh:PSXML_SEARCH_SUPP>
<!--Optional:-->
<xh:MSGID>TRAVEK_EBOOK001</xh:MSGID>
<!--Optional:-->
<xh:USERID>ABCUSER</xh:USERID>
<!--Optional:-->
<xh:PASSWORD>Connect#786</xh:PASSWORD>
<!--Optional:-->
<xh:OPTION>LIKE</xh:OPTION>
<!--Optional:-->
<xh:SUPPNO>ABDECS</xh:SUPPNO>
<!--Optional:-->
<xh:SUPPNAME>?</xh:SUPPNAME>
</xh:PSXML_SEARCH_SUPP>
</xh:PSXMLSearchSupplier>
</soapenv:Body>
</soapenv:Envelope>
I tried the same above with CURL request and got that working, i found that,following to be changed in my previous CURL request
, which on the raw tab in ReadyAPI
"SOAPAction: \"http://www.xmlhk.com/PSXMLSearchSupplier\"",
To work this with SOAP Client i just need to used multi dimensional array with $params['PSXML_SEARCH_SUPP'] shows below
$wsdl = "https://ps.gerrys.com.pk/PowerSuite/PSXMLSearch.asmx?WSDL";
$params['PSXML_SEARCH_SUPP'] = array(
'MSGID' => "TRAVEK_EBOOK001",
'USERID' => "GCONNECT",
'PASSWORD' => "Connect#786",
'OPTION' => 'LIKE',
'SUPPNO' => 'RK0048'
);
try {
$soap = new SoapClient($wsdl);
$data = $soap->PSXMLSearchSupplier($params);
echo "<pre>";
print_r($data);
echo "</pre>";
die();
}
catch(Exception $e) {
$e->getMessage();
var_dump($e->getMessage());
die();
}
