Load the system configuration file, and then load the system configuration through the engine. 2. Engine
First, set the configuration file, then test the system parameters, load the system module, obtain the website information file configured in, set the path required for the website, test the database parameters in the system configuration, load the library file, and finally It is to load the route to obtain the request address. The above process is just a set I wrote based on my own learning, but it lacks cache. How should the cache be set up specifically? The database test here is based on which type of database is configured, and then the encapsulation file for the operation of that type of database is loaded. 3. Routing The following is the last function above, which loads the controller file and obtains the request method according to the configuration file.
4. Controller The controller file is also quite simple. It just loads the model file and view file based on the address analyzed by the route.
Note: All the data that needs to be output in the model file is output through a class such as views, including all system parameters in the view file in the package. I don't know if this method is unnecessary. It turns out that I want to encapsulate all the data to be output. Other template files are also encapsulated with classes. As for how to write the cache in MVC, it is still a vague concept. When reading data, should the direction be to read the cache, then determine whether the cache exists, and then determine whether a cache needs to be established?

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
