Difference between Flask and PHP

The difference between Flask and PHP

First of all, PHP is a powerful server-side scripting language for creating dynamic interactive sites. Flask is a micro-Web framework developed based on Python, so Flask and PHP cannot be compared. If you need to compare, you can compare PHP and Python.

Flask introduction

Flask is a lightweight customizable framework written in Python language, which is more advanced than other frameworks of the same type. More flexible, lighter, safer and easier to use. It can be well combined with the MVC model for development. Developers work together, and small teams can complete the implementation of feature-rich small and medium-sized websites or Web services in a short time. In addition, Flask is highly customizable. Users can add corresponding functions according to their own needs, enriching and expanding functions while keeping the core functions simple. Its powerful plug-in library allows users to implement personalized websites. Customize and develop powerful websites.

Flask is a very popular web framework that uses the Python programming language to implement related functions. It is called a microframework. "Micro" does not mean putting the entire web application into a Python file. The "micro" in microframework means that Flask aims to keep the code simple and easy to expand. The Flask framework The main feature is that the core composition is relatively simple, but it has strong scalability and compatibility. Programmers can use Python language to quickly implement a website or web service. Generally, it does not specify objects such as databases and template engines, and users can choose various databases according to their needs. Flask itself does not provide form verification functions and can be freely configured during project implementation, thereby providing basic components of the database abstraction layer for application development and supporting functions such as form data legality verification, file upload processing, user identity authentication, and database integration. . Flask mainly includes two core function libraries, Werkzeug and Jinja2, which are responsible for business processing and security functions respectively. These basic functions provide a wealth of basic components for the web project development process. The Werkzeug library is very powerful and has relatively complete functions. It supports URL routing request integration and can respond to access requests from multiple users at one time. It supports cookie and session management, establishes long-term connection relationships through identity cache data, and improves user access speed. It supports interactive Javascript. Debugging to improve user experience; it can handle basic HTTP transactions and quickly respond to access requests pushed by the client. Jinja2 library supports automatic HTML transfer function, which can well control script attacks by external hackers. The system runs very fast. The page loading process will compile the source code into python bytecode, thereby realizing efficient operation of the template; the template inheritance mechanism can modify and maintain the template content to provide corresponding templates for users with different needs. There are currently many web frameworks for Python. In addition to Flask, there are also django, Web2py and so on. Among them, Diango is currently the most commonly used framework in Python. However, Django, like Java's EJB (EnterpriseJavaBeansJavaEE server-side component model), is mostly used for the development of large websites, but for the development of most small websites, using SSH (a JavaEE integration framework of Struts Spring Hibernat) is sufficient, and other Compared with other lightweight frameworks, the Flask framework has good scalability, which is irreplaceable by other web frameworks.
