Writing a Web Service Client
After the web service server is completed and verified, you can write a NuSOAP web service client. This is easier than creating a server, as you will see in this section. You may notice that in the following listing that a client instance is created by instantiating the soapclientNusoap class; to call the web service method, you should use the NuSOAP call method.
><?php
// Pull in the NuSOAP code
require_once('./nusoap-php5-0.9/lib/nusoap.php');
// Create the client instance
$client = new soapclientNusoap('http://localhost/php/SOAP_MESSAGES/server.php?wsdl', true);
// Check for an error
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
// At this point, you know the call that follows will fail
}
// Call the RectangleArea SOAP method
$result = $client->call('RectangleArea', array('L' => 40, 'l' => 20));
// Check for a fault
if ($client->fault) {
echo '<h2>Fault</h2><pre>';
print_r($result);
echo '</pre>';
} else {
// Check for errors
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
// Display the result
echo '<h2>Result</h2><pre>';
print_r($result);
echo '</pre>';
}
}
?>
