Analyse et résumé：

1. get_class() 函数用于获取Objet所属de当前类名。
2. get_parent_class() 函数用于获取Objetde直接父类名，S&#39;il n&#39;y a pas de classe parent, retournez false。
3. Par nom de classe parent，Nous pouvons l&#39;utiliser plus loin PHP de反射函数（comme get_class_methods）获取父类de方法信息。
4. Cette méthode convient au débogage、动态调用方法以及构建面向Objetde工具类ou框架。

Choses à noter：

- get_parent_class() Renvoie uniquement la classe Parent Direct，不会返回祖父类ou更高级别de父类。
- comme果需要判断Objet是否继承自某个特定类，Peut également être utilisé `is_a($object, 'ClassName')` ou `instanceof` Opérateur。
