Getting error during Salesforce integration in PHP - php

Question

I'm getting this error " Ooop! Error: Element {}item invalid at this location " at the time of calling Salesforce web service in PHP.
Bellow are my approaches:
require_once('salesforceAPI/soapclient/SforceEnterpriseClient.php');
require_once('salesforceAPI/soapclient/SforceHeaderOptions.php');
$sfdc = new SforceEnterpriseClient();
$SoapClient = $sfdc->createConnection('enterprise.wsdl.xml');
$loginResult = false;
$loginResult = $sfdc->login(USER, PASSWORD . SECURITY_KEY);
$parsedURL = parse_url($sfdc->getLocation());
define("_SFDC_SERVER_", substr($parsedURL['host'], 0, strpos($parsedURL['host'], '.')));
define("_WS_NAME_", 'salesforceAPI/Ctest');
define("_WS_WSDL_", _WS_NAME_ . '.xml');
define("_WS_ENDPOINT_", 'https://' . _SFDC_SERVER_ . '.salesforce.com/services/wsdl/class/' . _WS_NAME_);
define("_WS_NAMESPACE_", 'http://soap.sforce.com/schemas/class/' . _WS_NAME_);
$client = new SoapClient(_WS_WSDL_);
$sforce_header = new SoapHeader(_WS_NAMESPACE_, "SessionHeader", array("sessionId" => $sfdc->getSessionId()));
$client->__setSoapHeaders(array($sforce_header));
$method = $client->__getFunctions();
$wsParams = array('accName' => 'dasarathi');
$client->cInsert($wsParams);
I have no clue for solution.

Answer 1

It was a file path issue. Below is the rectification:
define("_WS_NAME_", 'salesforceAPI/Ctest');
// there is no such path http://soap.sforce.com/schemas/class/slesforceAPI/Ctest
define("_WS_NAMESPACE_", 'http://soap.sforce.com/schemas/class/' . _WS_NAME_);
I just redeclared the WS_NAME constant:
define("_WS_NAME_", 'Ctest');
