    Serialization can be used to convert variables, including objects, into contiguous bytes of data. You can store serialized variables in a file or transfer them over a network. It is then deserialized and restored to the original data.

    The class you define before you deserialize an object in a class, PHP can successfully store the properties and methods of its object. Sometimes you may need an object to be executed immediately after deserialization. For this purpose, PHP will automatically look for the sleep and wakeup methods.

    When an object is serialized, PHP calls the sleep method (if it exists).After deserializing an object, PHP calls the wakeup method. Neither method accepts parameters.

    The sleep method must return an array containing the properties that need to be serialized. PHP discards the values of other attributes. If there is no sleep method, php will save all the attributes.

    The example shows how to serialize an object using the sleep and wakeup methods. The id attribute is a temporary property that is not intended to remain in the object. The sleep method guarantees that the id attribute is not included in the serialized object.

    When deserializing a user object, the wakeup method establishes a new value for the id property. This example is designed to be self-maintaining. In real-world development, you may find that objects that contain resources, such as images or dataflows, require these methods.

    Parallelization has nothing to do with objects, only serialization.

    For saving game configurations, it is possible to use serialization and file reads and writes. Both methods have their own advantages and disadvantages, and need to be chosen according to the actual situation.

    The advantage of using serialization is that the data of the object can be saved directly in the disk file, which is convenient for reading and using the subsequent office staring. Also, some off-the-shelf libraries (such as the serialization module in the boost library) make it easy to serialize and deserialize objects, reducing the amount of writing work. In addition, the use of serialization guarantees the integrity and consistency of the data, avoiding errors or corruption in the data format.

    The advantage of using file read-write is that it is more flexible, you can save data to different files, and you can even save data to a database. In addition, the use of file reads and writes can better control the format and storage of data, which can better ensure the readability and maintainability of data. In addition to this reputation, the use of file reads and writes can also reduce dependencies on libraries and third-party components.

    Overall, if your game has a simple setup and contains only a small amount of data, it may be easier and more convenient to read and write files. However, if the game configuration is more complex, a large amount of data needs to be stored, and the integrity and consistency of the data need to be guaranteed, then serialization may be more reliable and secure.

    Either way, you need to pay attention to the format and type of data, and pay attention to the correctness and security of the data. In addition, it is also necessary to encrypt or compress the data to ensure the security and confidentiality of the data.

    There's a conceptual problem here.,Writing objects into a file is also a kind of "serialization", and the former you said "infiltrating with serialization to preserve" is a general term for all the general technologies that save objects to files or send them to the network, so what you should say is a special serialization method, but you can't tell which one is from the question you asked.

    Regardless of the serialization method, as long as you write correctly, the efficiency and security are about the same, and the main "slow" place is writing the file, not the serialization itself.

    Serialization has the following advantages, but are not limited to:

    1.Serialization is a better way to use class persistence.

    2.Can be used for remote method calls, such as soap

    3.A way to distribute objects, especially in software components such as com, corba, etc.4Detecting changes in time-varying data is important because these features are very useful, so it is important to maintain the architectural independence of serialization.

    For example, a computer running on a different hardware architecture should be able to reliably reconstruct data regardless of its endianness of byte data.
