What are common pitfalls when trying to integrate a new PHP class into XAMPP or a web server?

One common pitfall when trying to integrate a new PHP class into XAMPP or a web server is not properly including the class file in your PHP script. To solve this issue, make sure to use the correct file path when including the class file in your script.
