Were you able to figure this out? Your code seems to work for me. I assume you were using PEAR SOAP/Client? Here's the full script that I tried:
Code:
require_once( "SOAP/Client.php" ); # PEAR SOAP/Client
#date_default_timezone_set('UTC');
$DirectFlight_Authentication = array( */
'user' => 'sampleUser',
'pass' => 'abc123abc123abc123abc123abc123abc123',
);
$wsdl_url = 'http://flightxml.flightaware.com/soap/FlightXML2/wsdl';
$WSDL = new SOAP_WSDL($wsdl_url,$DirectFlight_Authentication);
$soap = $WSDL->getProxy();
$query = "-origin KRDU";
$result = $soap->Search($query,15,0);
print_r($result);
