In-depth analysis of the observer pattern in PHP object-oriented programming
Article Introduction:In-depth analysis of the Observer pattern in PHP object-oriented programming The Observer pattern is a commonly used design pattern used to achieve loose coupling between objects in software systems. Its core idea is: an object (called an observer or subject) maintains a list of objects (called observers) that depend on it. When the state of the observed object changes, it will automatically notify all observers. . In this way, the observer pattern can implement a one-to-many relationship between objects. When an object changes, all related objects will be notified and can

What is observability? Why is it important?
Article Introduction:As technology evolves, so does the need for more efficient and accurate system monitoring. Traditional system monitoring only provides limited visibility into the system, which makes it challenging to identify and troubleshoot errors when they occur. This is where observability comes in. Observability is a new method of system monitoring that provides greater visibility into system performance and helps quickly identify and resolve issues. Let’s take a look at what observability is and why you should use it. What is Observability? Observability is a vital tool for software developers. It provides insight into system behavior and helps troubleshoot problems when they arise. Systematically collecting, analyzing, and correlating observability data gives developers real-time visibility into how their applications are operating.
