Well, the error states the problem: You use $this out of object context. (You cannot declare a variable with name "$this")

If you want to use an object of a class you must instantiate it before you can access its methods and properties:
class SomeClass {
public $anything = 'x';
public function something() {
// ...
}
//...
}

$someClassObj = new SomeClass();
$someClassObj->anything = 'X';
$someClassObj->something();dumpfi
