在php中使用Web服务（首次）

Question

It took me a while to get soap configured in php. Now I'm just trying to learn about it. I'm using the web service here to learn:

http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=19

It says the WSDL is here:

http://www.webservicex.net/stockquote.asmx?wsdl

and this is my code:

$client = new SoapClient('http://www.webservicex.net/stockquote.asmx?wsdl');
$result = $client->getQuote("AAPL");
echo $result;

I'm getting an error saying "Object of class stdClass could not be converted to string". Now I realize that $result is an object, and I'm wondering how do I access data that the server populated? I tried to understand the WSDL but I'm getting nowhere. Is it supposed to be something like:

$result->price

? (That doesn't work by the way...)

Ideas?

Answer 1

1. When curious about datatypes from the soapserver, use the SoapClient->__getTypes() & SoapClient->__getFunctions() methods
2. If you return is still not clear, var_dump() your return and examine it.
