1.1 Research Background
Nowadays, with the rapid development of science and technology, computers play an important role in all fields of life, especially in information management. To use it in practice, to continuously facilitate people's life from an innovative perspective, to promote the learning of new knowledge, to cultivate self-learning ability, and to exercise the ability of hands-on practice. The previous community forum management should also get rid of the manual management mode and use computer technology for information management. Therefore, the community forum management system designed by this system combines text and images, and can realize functions such as online music playback. Bloggers can also communicate with each other online, which is also an important element of the community forum management system. After several years of practice and summary, community forum management is developing in a deeper direction. Therefore, it is imminent for people to improve the system function. With the rapid development of science and technology, the community forum management system must constantly improve the complexity of its work process, diversification, complex management, cumbersome equipment maintenance and other existing problems. Therefore, it is necessary to use the computer to be competent for the management of community forums, so that the community forum management system is more accurate, convenient and fast.
Therefore, it is very necessary to develop a high-efficiency, low-error community forum management system. The main purpose of this system is to realize the digitalization of the community forum management system in an all-round way. The administrator can fully grasp the blogger and all information, and the blogger can have an intuitive understanding of the community forum.
1.2 Current status of community forum management
Nowadays, some websites do not provide community forum management services, that is, although the websites have been implemented, the management power of relying on the traditional mode is far from enough, so the community forum management work of many websites only stays in the traditional mode management services. At the same time, many websites have limited funds and lack of professional staff, so the management methods of community forum management are relatively backward, and it is difficult to improve the popularity of the website, and at the same time, it cannot provide better information for bloggers. For perfect service. In the past, the management of community forums was done manually through manual management records and operations, which was not only troublesome and trivial, but also often made mistakes, which brought great inconvenience to the majority of bloggers, and also required a lot of manpower, material and financial resources, which greatly wasted the website H. With the rapid development of the network, people gradually hope that the community forum management system can provide more reasonable and perfect services. Now, good community forum management has also become the key for bloggers to choose a community forum management system.
1.3 Functions realized by the system

Chapter 2 Development Technology and Environment Configuration
A community forum management system developed with PHP as the development language, using the current advanced Vscode as the system development tool, and MySQL as the background database.
2.1 Introduction to PHP language
PHP, formerly known as Hypertext Preprocessor. It is an embedded language, which executes the scripting language embedded in HTML on the server . It is a bit like the C language style and is widely used. Hypertext Preprocessor mixes Perl, C, PHP and its own innovative syntax. Synthesized to perform dynamic web pages faster than the former. Compared with other languages , embedded in HTML for execution is more efficient than CGI that completely generates HTML; PHP can also execute compiled code , encrypt, optimize code operation, and make code run faster. The function of PHP is very powerful, and some functions of CGI can be realized by PHP, and it can support almost all popular databases and operating systems. C, C++ program PHP is also an extension that can be used!
PHP includes: professional focus, open source code, free use, strong cross-platform, fast, object-oriented, high efficiency, image processing, etc.;
2.2 Introduction to mysql database
Using MYSQL's data independence, security and other characteristics to operate data in software projects can ensure the accuracy of data and reduce the application development time of programmers.
The feature of MYSQL is that it supports multi-threading, which can make full use of system resources conveniently, effectively improve the speed, and also provides various ways to connect to the database; MYSQL is relatively weak in function and small in scale, but the requirements of this system are not high. MYSQL can fully satisfy the use of this website.
Using MYSQL to establish a system database is not only conducive to the early integration of data processing services, but also conducive to the development of the latter two types of data expansion operations.
2.3 MySQL environment configuration
(1) The data of this system uses MySQL, so you need to install MySQL to the specified directory. If you download the non-installed MySQL compressed package, you can directly decompress it to the specified directory. Then click on the file C:\Program Files\MySQL\bin\winMySQLadmin.exe where C:\Program Files\MySQL is the MySQL installation directory. Enter the initial blogger and password of winMySQLadmin (Note: This is not the blogger and password in MySQL). Don’t worry about filling in whatever you want. After confirming, a traffic light icon will appear in the task startup bar in the lower right corner. The red light means the service is stopped, and the green light is on. It means the service is normal, left click on this icon ->winnt->install the service to install the service, then left click on this icon ->winnt->start the service to start the MySQL service.
(2) Modify the root password of the MySQL database. Use cmd to enter the command line mode and enter the following command:
cd C:\Program Files\MySQL\bin
MySQLadmin -u root -p password 123
Press Enter and Enter password: appears, which is to enter the original password. The password was empty when it was first installed, so press Enter directly. At this time, the password of the account root in MySQL is changed to 123 and the installation is complete.
2.4 B/S Architecture
The B/S system can be used through a computer that can access the Internet. Its biggest advantage is that it does not need to install special software. First, the browser sends a request to the server, and then the server processes the request and returns the information to the browser. There is no need to access and calculate the data again, as long as it is responsible for displaying the data to reduce the requirements. If the client is like a "thin man", the server will become more and more "fat". Compared with the C/S architecture, the biggest difference between the B/S architecture and the C/S architecture is that the application software of the B/S system uses a web browser as a platform for interacting with bloggers, while the C/S needs to develop a dedicated application program.
Currently, there are two popular structures of MIS system: C/S and B/S.
C/S structure system: C/S structure is the client server structure, which can send tasks to the Client and Server to make full use of the advantages of the hardware environment at both ends to reduce the communication cost of the system. The main role of the client is to handle human-computer interaction, execute client applications, collect data, and send task requests to the server. The basic role of the server is to execute the background program. It mainly responds to the client's request application. In addition, its role also includes: shared management of data service reservation storage system, communication management, file management and so on.
B/S structure system: This network structure simplifies the client and concentrates the center of system function realization on the server. In this mode, only one browser is needed. This structure hands a lot of work to the WEB server, only requests WEB services through the browser, and then returns information according to the request.
Usually used inside the website, using C/S. The use of B/S is not limited to the case of intranet. Considering a series of requirements of this management system, the system is developed using B/S structure.
Chapter 3 System Analysis and Design
3.1 Feasibility analysis
For a complete system, feasibility analysis is a must, because it is related to the survival of the system, and the meaning of development is analyzed.
