Oggetti ... valori

[ricman]

Scusate sono poco pratico con gli oggetti...
Da output come questo come si memorizza su variabili il valore?
(tipo echo $Symbol; dovrebbe restituire USDPKR)

stdClass Object
(
    [GetRealTimeCrossRateResult] => stdClass Object
        (
            [Outcome] => Success
            [Message] => Cross-rate calculated by converting to EUR.
            [Identity] => Header
            [Delay] => 0.009
            [Symbol] => USDPKR
            [Type] => RealTime
            [From] => stdClass Object
                (
                    [Symbol] => USD
                    [Name] => United States Dollar
                )

            [To] => stdClass Object
                (
                    [Symbol] => PKR
                    [Name] => Rupee
                )

            [Date] => 12/9/2010
            [Time] => 11:45:49 AM
            [Rate] => 85.8019093105
            [Bid] => 85.6712937893
            [BidTime] => 11:45:49 AM
            [Ask] => 85.9325426138
            [AskTime] => 11:45:49 AM
            [Text] => 1 United States Dollar = 85.80191 Rupee
        )

)

Tale output è ottenuto con delle chiamate Soap tipo queste:

$xignite_header = new SoapHeader('http://www.xignite.com/services/','Header', array("Username" => "nome","Password" => "password", "Tracer" => ""));    
$wsdl = new soapclient('http://www.xignite.com/xCurrencies.asmx?WSDL');    
// attach SOAP header
$wsdl->__setSoapHeaders(array($xignite_header));    
// call the service: pass the parameters and name of the operation
$input_params = array('From' => "USD", 'To' => "PKR");    
$result = $wsdl->GetRealTimeCrossRate($input_params);    
// assess the results    
if (is_soap_fault($result)) {
     echo '<h2>Fault</h2><pre>';
     print_r($result);
     echo '</pre>';
} else {
     echo '<h2>Result</h2><pre>';
     print_r($result);
     echo '</pre>';
}
