ผมใช้งาน nusoap ไม่ได้ใครก็ได้ช่วยดูหน่อยครับ ทั้งๆๆก็น่าจะถูกแล้วนะ

require "function.php";
	require "lib/nusoap.php";
	
	$server = new soap_server();
	
	$server->configureWSDL("demo","urn:demo");
	 
	$server->register('price',
			   array("name" => "xsd:string"), 
			   array("return" => 'xsd:string')
			   );
	 
	$POST_DATA = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : '';
	$server->service($POST_DATA);

function price($name)
{
	return $name;
}

require "lib/nusoap.php";
	$client = new nusoap_client("http://localhost/nusoap/service.php?wsdl"); 
	$data = $client->call("price",array("name" => "Weerachai Nukitram")); 
	echo $data;
