What is the difference between calling a method within a class instance and calling a standalone function in PHP, as seen in the code snippet?

When calling a method within a class instance in PHP, you need to use the arrow operator (->) to access the method. On the other hand, when calling a standalone function, you simply use the function name followed by parentheses. To fix the issue of calling a method within a class instance, make sure to use the arrow operator to access the method.
