2. PHP object-oriented - detailed code explanation of object serialization serialize(), __sleep(), __wakeup()

#Introduction: Sometimes it is necessary to transmit an object over the network. In order to facilitate transmission, the entire object can be converted into a binary string, and when it reaches the other end , and then restored to the original object. This process is called serialization (also called serialization). Just like we now want to transport a car to the United States by ship, because the car is relatively large, we can The car is disassembled into small parts, and then we ship these parts to the United States on wheels, and then assemble the parts back into the car. There are two situations where we must serialize the object. The first situation is to serialize an object.

5. Python thread organization

#Introduction: Threads have five states: new, ready, running, blocked, and dead. There are three situations of blocking: Synchronous blocking refers to the state of competing locks. When a thread requests a lock, it will enter this state. Once the lock is successfully obtained, it returns to the running state; Waiting blocking refers to the state of waiting for notification from other threads. After the thread obtains the conditional lock , calling "wait" will enter this state. Once other threads send notifications, the thread will enter the synchronous blocking state and compete with the lock again; and other blocking refers to calling time.sleep(), anotherthread.join(...

7. php—Serializable interface

Introduction: Custom serialization interface. Classes implementing this interface will no longer support __sleep() and __wakeup(). Whenever an instance needs to be serialized, the serialize method will be called. It will not call __destruct() or have other effects unless this method is called programmatically. When data is deserialized, the class will be aware and the appropriate unserialize() method will be called instead of calling __construct(). If you need to execute the standard constructor, you should handle it in this method.
