About WebService get the value, little brother ask for help
function Getline () {
$client = new SoapClient (' Http://www.ungb.com/sky/LineService.asmx?WSDL ');
try {
$result = $client->getlistline ();
Print_r ($result);
return $result;
}catch (SoapFault $e) {
return-1;
}
}
?>
I get the null value through the above code, but I use the SOAPUI test, the interface is good, you can get the value.

This thing made me depressed to die, beg that elder brother to help solve, thank you .......
