I want to use some online web service. but am not expert in thsi field.

a tutorial on the nety said someth9ng like this..

require_once('nusoap.php');

$wsdl="http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('country1'=>'usa', 'country2'=>'canada'); 
echo $client->call('getRate', $param);

it was using nuSoap library. nut when viewing this page after coding it. nothing appears on screen.

what is the porblem

Try placing the code into PHP like this then run it.

<?php
require_once('nusoap.php');

$wsdl="http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('country1'=>'usa', 'country2'=>'canada'); 
echo $client->call('getRate', $param);
?>

Well I can tell you $param is an associative array and if you were to just see what it equals in the code you have shown so far by doing echo $param ; The output would be Array So the function from the class $client named call() probably doesn't work correctly when presented with a value of Array I don't know what the two variables that call()expects, it might have defaults that don't really produce a result.

What does that function look like?

if you dont know something about NuSOAP or PEAR_SOAP libraries , no use of posting replies.

If you are not going to be civil and help others help you, no use posting a question.
