I would like to use php to call a c# webmethod but it's unsuccessful - why?

    try {

    $client = new SoapClient($VerifyUser);

    $params = array( 
        'Merchant_id'  => $tbl_result['tbl_merchant']['data'][0]->Merchant_id, 
        'Merchant_code' => $tbl_result['tbl_merchant']['data'][0]->Merchant_code
    );

    $response = $client->VerifyUser(
        array(
            'Merchant_id'=>$tbl_result['tbl_merchant']['data'][0]->Merchant_id
        )
    )->VerifyUserResult;
} catch (Exception $e) {
    print_r($e->getMessage());
}

////////////// C#

    [WebMethod]
    public static string VerifyUser(string Merchant_id)
    {
        return "";
    }

There is an error as below:

Function ("VerifyUser") is not a valid method for this service

Now i change to below:

$clsUser = array( 'xxx' => 'xxx' ); 
$urlWebService = "xxx.asmx?WSDL"; 
$response = WebSoapClient("VerifyUser", $urlWebService, $clsUser); 


function WebSoapClient($function ,$url, $data = array() ) { 
    $response = null; 
    try { 
        $client = new SoapClient($url); 
        $response = $client->__soapCall( $function, $data ); 
    } catch (Exception $e) { 
        ErrorLog("WebSoapClient->". $function . " - " . $e->getMessage()); 
    } 
    return $response; 
} 


/C# 
[WebMethod] 
public string VerifyUser(clsUser clsUser) { 
    //xxx...
}

but in C# param is null...

  • Is the webmethod in an asmx service or aspx, or what? Are you sure it's definitely a SOAP interface? Is there a WSDL? Commented Nov 17, 2021 at 9:54
  • Yes it is WSDL. Now i change to below: $clsUser = array( 'xxx' => 'xxx' ); $urlWebService = "xxx.asmx?WSDL"; $response = WebSoapClient("VerifyUser", $urlWebService, $clsUser); function WebSoapClient($function ,$url, $data = array() ) { $response = null; try { $client = new SoapClient($url); $response = $client->__soapCall( $function, $data ); } catch (Exception $e) { ErrorLog("WebSoapClient->". $function . " - " . $e->getMessage()); } return $response; } /C# [WebMethod] public string VerifyUser(clsUser clsUser) { } but in C# param is null... Commented Nov 18, 2021 at 10:39
  • Ok. So, what was the result of that change? P.s. if you have new code to share, please edit your question - do not put code in these comments where you cannot easily format it, thanks.
