Course Introduction：JSON is a universal lightweight data storage and exchange format that is independent of programming languages. It is written based on JavaScript object syntax and is very suitable for Web development. Ajax is an asynchronous data loading technology that allows users to obtain data without leaving the current page. The user experience is excellent. This course combines json and ajax technologies to demonstrate the application scenarios of these two technologies with examples (the knowledge of php and mysql involved can be temporarily neglect)

Course Introduction：Design pattern (Design pattern) is a set of classified and cataloged summary of code design experience that is used repeatedly, known to most people. The purpose of using design patterns is to reuse code, make the code easier to understand by others, and ensure code reliability. There is no doubt that design patterns are win-win for ourselves, others, and the system; design patterns make code writing truly engineering; design patterns are the cornerstone of software engineering, just like the structure of a building.

Course Introduction："Ajax Principles Detailed Video Tutorial" The core of Ajax is the XMLHttpRequest object, referred to as XHR. It is used to enable the browser to request additional data from the server without unloading the page, which greatly improves the user experience. Prior to this, this technology actually existed and was implemented by some people, but it was not popular and was not supported by browsers. However, after that, IE5 introduced XHR objects for the first time and supported ajax technology, which was subsequently supported by all browsers.

Course Introduction：Three major principles of ppt design: MagicSeven principle, KISS principle, and 10/20/30 principle. Making PPT is not the same as designing PPT, the design part only accounts for 20%; the only purpose of making PPT is to successfully convey the key points; don't treat PPT as Word, and only show one kind of information to the audience at a time.

Course Introduction：PHP Design Patterns: Relationship to Design Principles Introduction Design patterns are reusable solutions in software development that are used to solve common problems. They are based on design principles such as SOLID (single responsibility, open-closed, dependency inversion, interface isolation, Liskov substitution). Understanding design principles is crucial to effectively applying design patterns in PHP. Design Principle Single Responsibility Principle (SRP): Each class or module should be responsible for only one function. This enhances maintainability and testability. Open-Closed Principle (OCP): Software should be easy to extend but difficult to modify. This means that interfaces and abstract classes should be used instead of concrete classes. Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules. Instead, they should rely on pumping
