What are the best practices for handling static properties and methods in PHP classes?

When dealing with static properties and methods in PHP classes, it is important to ensure proper encapsulation and avoid global state. One best practice is to use static properties and methods sparingly and only when necessary, as they can introduce tight coupling and make code harder to test and maintain. Additionally, consider using dependency injection or other design patterns to achieve the desired functionality without relying on static elements. 

class Example {
    private static $staticProperty;

    public static function setStaticProperty($value) {
        self::$staticProperty = $value;
    }

    public static function getStaticProperty() {
        return self::$staticProperty;
    }
}
