What does it mean when I get this error?

Call to a member function getVarNames() on a non-object in wrapper.php on line 66.

I took a job integrating existing php code for a GIS Maping Co.

Now when i got the code and db I noticed they used classes ( which I know kinda what they are, but not how to use them really. ) I've read the online documentation and if my understanding is correct then it works like this:

defining a class:

class MyClass{

$someVarDeclarations

someFunc1(args)
{}

someFunc2(args)
{}

}
}

Accessing a class to get variables from a function within a class:

$myVar = $myClass->someFunc1(args);

is there something i'm missing here?

sounds like your have not created an object instance of the class.

which means....?

...you need to create an object based on whatever class contains the member function getVarNames() using the new operator. you should do some basic reading on PHP Classes and Objects. be advised that OOP implementation is quite different depending on your PHP version (4 vs 5).
