What this error means in PHP?

Call to a member function getStrippedName() on a non-object

It's an oop (Object Orientated Programming) error saying that you are treating a function as an object. Mainly it says the function getStrippedName() is not an oop object and has been called as an oop object. So there are 2 solutions. You could convert the function getStrippedName() into an object or you could use a non-oop method of calling the function.
Examples are:

<?
// oop - example 1
$var = new getStrippedName();

// oop - example 2
$var->getStrippedName();

// non-oop
$var=getStrippedName();
?>

So to make your script work, you will need to use the third example in the above box where you don't use the arrow or the word 'new'.
Hope it helps.
