While designing a singleton mode, it is easy to design a class type that conforms to the principle of the singleton pattern, but considering the garbage collection mechanism and thread safety, we need to think more. Some designs can barely meet the project requirements, but when it comes to multithreaded design. Regardless of thread safety, it will inevitably bring hidden trouble to our programming. Here, we don't describe what a singleton

Does PHP have a configuration or a way to turn thread-safe mode on? When you run multiple scripts, you are using file locks to control parallelism, what better way to get multiple PHP scripts to communicate? Is there any way to ensure that the PHP script is running in a thread-safe manner? Reply content: Does PHP have a configuration or a way to turn thread-

Baidu definition : Single case mode is a commonly used software design mode. In its core structure, there is only one special class that is called a singleton. The singleton mode ensures that there is only one instance of a class in the system.Wikipedia : In Software engineering, a singleton is a mathematical concept for implementing a singleton, and the instanti

A single-piece mode, also known as a singleton mode, is used to create unique objects that can have only one instance.The class diagram of a single-piece pattern is the simplest of all patterns in the class diagram--only one class. Although the single-piece mode is simple from the point of view of class design, there are still some problems in the implementation,

Singleton mode is to ensure that a class has only one instance and is easy to access outside. So generally only the constructor, copy function, destructor, assignment function, variable name into private. You can then use a Get function to access the provided interface. Consider thread safety and lock it up.First, lazy mode:1. Lazy
