In PHP, what is the significance of declaring methods as public, protected, or private within a class?

Declaring methods as public, protected, or private within a class in PHP determines the visibility of these methods to other classes and subclasses. - Public methods can be accessed from outside the class. - Protected methods can only be accessed within the class itself and any subclasses. - Private methods can only be accessed within the class itself. This visibility control helps in encapsulation and ensures that the class's internal implementation details are not exposed to external code.

class MyClass {
    public function publicMethod() {
        // Code accessible from outside the class
    }

    protected function protectedMethod() {
        // Code accessible within the class and subclasses
    }

    private function privateMethod() {
        // Code accessible only within the class
    }
}
