How can a method within a class be called properly in PHP?

To call a method within a class in PHP, you need to create an instance of the class and then use the arrow operator (->) to access the method. Make sure the method is public or protected to be accessible from outside the class. You can also use the static keyword if the method is a static method. Example:

class MyClass {
    public function myMethod() {
        echo "Hello, World!";
    }
}

$instance = new MyClass();
$instance->myMethod();
