Getting white screen, even with error reporting on, when trying to test a SOAP transaction.

<?php
ini_set('display_errors',1);  
error_reporting(E_ALL);
require_once('lib/nusoap.php');
$client = new nusoap_client('https://sso-test.fas.gsa.gov/mpdev/navigator/wsdl','wsdl');
$result = $client->call('retrieveContractVehicles', array(
			'commodity' => 'LAPTOP',
			'location' => 'CONUS',
			'lsaStates' => 'VA',
			'oconusStates' => 'ALASKA',
			'socioEconomicObjective' => 'SB',
			'agencyCode' => '006'));
?>

Ask the publisher to furnish the data via a RESTful interface design.  Nobody uses SOAP anymore - most services abandoned it in the last millennium!  It's just too hard to program and debug when you have to know what is happening on a computer you cannot see.  In contrast to SOAP, I have never met anyone who could not immediately understand and use REST services.

The web service was offline. That might been a factor, albeit I didn't get an error thrown up on screen.

Yep, that's just one of the many problems with using SOAP in PHP.

Discovered it was a web service connection issue.
