Pulling data from a class not working as expected...???

Asked by angelleye in PHP Scripting Language

Tags: PHP

I've got a simple class setup to help me build PayPal SOAP requests.  I've included the top portion of this class  as a code snippet.  As you can see I'm storing my API credentials outside of the web root and parsing the values within the class.

When I include this class into another PHP file and then do:

$ppSession = new PayPalSession(true);
echo $ppSession -> SOAPHeader;

I get the SOAPHeader data except the credentials are blank.  For some reason it's not going through the process of opening up that XML file and parsing out the values or something like that.

When I build functions inside this class to generate requests and then do something like:

$SOAPResponse = $ppSession -> GetExpressCheckoutDetails($Token);

That works perfectly and loads the response as expected.  For this particular request, though, there are LOTS of options and I don't really have the time right now to develop this function to handle all possible scenarios.  Therefore, I've simply generated this one request inside the script itself but the class isn't working the same way for me.

I don't understand why the class runs differently when I just pull values out of it rather than running functions inside of it.  At first I was thinking it must have something to do with the $this -> variable but the SOAPHeader itself is inside one of those and it does display, just without the credentials.

Any information on what I can do here would be greatly appreciated.  Thanks!
