ASP.NET/C# client to consume a PHP/MYSQL web service (WSDL)

Question

I am trying to access a webservice (two files below). The client is using ASP.NET/C# for their web architecture. I can add the web reference but somehow I cannot generate a proxy class for the wsdl file. The aim is to use the function in the server.php file so that I can use the xmlstring to display the data on the ASP.NET website. Any help would be very appreciated. Many Thanks

server.php file. This file has a php function which extracts data from a mysql db and the function returns the data as an XML string.

<?php
//WEB SERVICE FUNCTION TO EXTRACT DATA FROM CLIENT B INTO XML FORMAT
function getXML()
{
//CONNECT TO THE DATABASE SERVER
$dbserverIP = "xxxxxxx";
$dbusername = "xxxxxxx";
$dbpassword = "xxxxxxx";
$dbconnection = mysql_connect($dbserverIP,$dbusername,$dbpassword)  
or die ("The connection to the database server failed.");

//CONNECT TO THE DATABASE
$dbname = "xxxxxxxx";
$dbselectok = mysql_select_db($dbname,$dbconnection)
or die ("The connection to the database failed.");

//QUERY THE DATABASE
$sqlquery = "SELECT * FROM videogames";
$sqlresult = mysql_query($sqlquery,$dbconnection)
or die ("Error in executing the SQL statement");

//CREATE XML STRING
$xmlstring = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n";
$xmlstring.= "<videogames>";

while ($row = mysql_fetch_array($sqlresult))
{
    $xmlstring .= "\t<game>\r\n";
        $xmlstring .= "\t\t<gametitle>" .$row["gametitle"]. "</gametitle>\r\n";
        $xmlstring .= "\t\t<genre>" .$row["genre"]. "</genre>\r\n";
        $xmlstring .= "\t\t<year>" .$row["year"]. "</year>\r\n";
        $xmlstring .= "\t\t<platform>" .$row["platform"]. "</platform>\r\n";
        $xmlstring .= "\t\t<agerating>" .$row["agerating"]. "</agerating>\r\n";
        $xmlstring .= "\t\t<price>" .$row["price"]. "</price>\r\n";
    $xmlstring .= "\t</game>\r\n";
}

$xmlstring.= "</videogames>";

//WRITE XML STRING TO EXTERNAL FILE
$filename = "videogames.xml";
$fileaccessmode = "w";
$fptr = fopen($filename,$fileaccessmode);
fwrite($fptr,$xmlstring);
fclose($fptr);

//FREE UP MEMORY
mysql_free_result($sqlresult);
mysql_close($dbconnection);

return $xmlstring;

}

//CODE TO DISABLE THE WSDLE CACHE
ini_set("soap.wsdl_cache_enabled","0");

//DEFINE SOAP SERVER INSTANCE AND RELATED WSDL FILE
//THE service.wsdl FILE IS IN THE SAME FOLDER AS THIS server.php FILE
$server = new SoapServer("service.wsdl");

//ADD FUNCTION TO THE SERVER INSTANCE
$server->addFunction("getXML");

//ACTIVATE THE SOAP HANDLER
$server->handle();

?>

This is the WSDL file linked to the server.php file.

<?xml version ='1.0' encoding ='UTF-8' ?>
