[RESOLVED] Call to a member function on a non-object

What does this mean? Ive included a file inside my php and im trying to access a function inside of it..not sure whats goin on..

edit*
figured it out.

When including a file, you need to initiate a new class like so

PHP Code:

---

inc ('includes/class.myclass.php');
$myquery = new myclass(); 


---

A class is a template for an object, sort of like a mould. The object doesn't exist until you create it using the new operator.

$myquery = new myclass();

The above like is like saying, "create me an object using myclass as a tmeplate and assign its location to $myquery"
