Answer / Sohan Sagar Jha
In PHP, `__sleep` and `__wakeup` are magic methods used for serialization (converting an object into a format that can be stored or transmitted) and unserialization (recovering data from the serialized format). The `__sleep` method returns an array of properties that should be serialized while the `__wakeup` method is called after an object has been unserialized.
