What is a php framework?

The PHP framework is an infrastructure that can improve development efficiency, create more stable programs, and reduce developers' repetitive coding during the project development process; the PHP framework is an infrastructure that integrates the development processes of different Web systems. The common features and general functions are abstracted to form the basic architecture for developing Web programs.

What is php framework?

The PHP framework is an infrastructure that can improve development efficiency, create more stable programs, and reduce developers from repeatedly writing code during the project development process. The PHP framework abstracts the common and common functions in the development process of different Web systems to form the basic architecture for developing Web programs.

When developing Web systems, if developers conduct secondary development based on the PHP framework, they can greatly simplify the development process and quickly implement system functions. The PHP framework can promote the rapid development of Web systems, save time, reduce the amount of repeated code, and help beginners create standardized and stable Web systems.

php frameworks include: thinkPHP, laravel, yii, CakePHP, CodeIgniter, Zend, Symfony, Yii2, Phalcon, etc.

Framework, that is, Framework, is actually a semi-finished product of a certain application, or a series of components for people to choose to complete our own applications. In other words, using a framework to develop a program is like performing on a stage that has been set up by others. You don't have to worry about the cumbersome and low-level things like setting up a stage, so that you can devote yourself to how to perform better. For example, Microsoft's .NET Framework, using it to develop Windows applications will be much more efficient.

The same is true for the PHP development framework. The PHP development framework encapsulates the underlying operations and puts Web program development on the assembly line. In other words, PHP development framework helps facilitate Rapid Software Development (RAD). Using the PHP framework not only saves developers time, but also helps developers create more stable programs and reduces the developer's labor of repeatedly writing code. The PHP development framework allows developers to spend more time creating real Web programs instead of writing repetitive code.

PHP development framework mostly adopts the "Model-View-Controller" (MVC) architecture pattern. The MVC architecture first existed in desktop applications, where M refers to the data model, V refers to the user interface, and C refers to the controller. The purpose of using MVC is to separate the implementation code of M and V, that is, to isolate the business logic and the user interface. No matter which one changes, it will not affect the other. In the MVC architecture, the model is responsible for data, the view is responsible for presentation, and the controller is responsible for business logic. Essentially, MVC splits the development process of a program so that you can modify each independent part without affecting other parts, which makes writing PHP code faster and easier.
