Preserving session data between requests using PHP's SoapClient - php

Question

I have developed an ASP.NET Web Service that performs queries to a database. Now I am developing a PHP Web site that consumes the Web Service for anything that requires access to the database. I have written the following function which creates a new SoapClient to consume the Web Service:
function get_soap_client()
{
if (!file_exists('wsdl_path.txt')
return NULL;
if (!$file = fopen('wsdl_path.txt', 'r'))
return NULL;
$path = fgets($file);
fclose($file);
return new SoapClient($path);
}
I have already tested this function as means to get a client to a stateless Web Service, and it does work. For example, this is my Web site's login function (whose control flow is not affected by state):
function try_login($user, $pass)
{
$client = get_soap_client();
// ASP.NET Web Services encapsulate all inputs in a single object.
$param = new stdClass();
$param->user = $user;
$param->pass = $pass;
// Execute the WebMethod TryLogin and return its result.
// ASP.NET Web Services encapsulate all outputs in a single object.
return $client->TryLogin($param)->TryLoginResult;
}
Which in turn calls the following WebMethod:
[WebMethod(EnableSession = true)]
public bool TryLogin(string user, string pass)
{
SqlParameter[] pars = new SqlParameter[2];
pars[0] = new SqlParameter("#User", SqlDbType.VarChar, 20);
pars[0].Value = user;
pars[1] = new SqlParameter("#Pass", SqlDbType.VarChar, 20);
pars[1].Value = pass;
// The Stored Procedure returns a row if the user and password are OK.
// Otherwise, it returns an empty recordset.
DataTable dt = Utilities.RetrieveFromStoredProcedure('[dbo].[sp_TryLogin]', pars);
if (dt.Rows.Count == 0) // Wrong user and/or password
{
Context.Session.Abandon();
return false;
}
else
return true;
}
However, I don't know whether the Web Service's Context.Session data is preserved between consecutive requests made from SoapClient objects retrieved by get_soap_client(). So I have the following questions:
Is the Web Service's Context.Session data preserved between consecutive requests made from a SoapClient object retrieved by get_soap_client()?
Is the Web Service's Context.Session data preserved between consecutive requests made from different SoapClient objects retrieved on the fly as I need them?
If the answer to the previous question is "no", is there any way to serialize the SoapClient's session data into a PHP state variable?

Answer 1

Ah, you mean is it sending the SESSION ID. I imagine you'll need to call __setCookie manually to set a cookie with the SESSION ID to your web service.
