How can I prevent XSS with HTML/PHP?

Solution
Basically you need to use the function `htmlspecialchars()` whenever you want to output something to the browser in HTML context.
The correct way to use this function is something like this:
echo htmlspecialchars($string, ENT_QUOTES, 'UTF-8');

How do I prevent XSS (cross-site scripting) using just HTML and PHP? I've seen numerous other posts on this topic, but I have not found an article that clear and concisely states how to actually prevent XSS.
