PHP SOAP to .NET generates object reference not set

[csbdeady]

I am trying to use SOAP in PHP to retrieve data via an MS .NET web service for work. However I see the following error message:

Object reference not set to an instance of an object.

I have read the help available at

http://uk.php.net/manual/en/function.soap-soapclient-soapcall.php#76831

which describes this exact problem, but do not understand the advice given - or rather I have tried using the example given with the WSDL I will be using and it still generates the above error.

I would be most grateful if someone could explain in lamens terms exactly how I set the instance of the object that needs to be passed to the .NET service.

Many thanks

There must be a line number with that message that tells you where this error has occurred.

In that line, you will see an object variable with a -> operator. This -> is used to call a property or a method on that object. The problem here is that this variable does not contain an object at all. So you could reproduce it with code like:

$test = 2; // Not an object
echo $text->Whatever(); // Gives the error

This also means that the real error is earlier in your code, or that the code relies on error checking being set to hear-no-evil-see-no-evil mode.
