What are some potential pitfalls of using public access methods in PHP classes?

Using public access methods in PHP classes can lead to potential pitfalls such as exposing internal implementation details, making it harder to maintain and refactor the code, and increasing the risk of unintended side effects when the methods are called directly by external code. To mitigate these issues, it is recommended to use private or protected access modifiers for methods that should not be accessed from outside the class. 

class MyClass {
    private $data;

    public function getData() {
        return $this->data;
    }

    public function setData($data) {
        $this->data = $data;
    }
}
