Design And Implementation Of Teacher-student Bi-directional Selection System Based On PHP And MySQL

After entering the 21 st century,computer technology especially computer network now has become almost an indispensable part of people in work and life,the network is a product of the development of science and technology,is also the symbol of the information age.And the website is a kind of communication tool,people can use the website not only to publish the information they want to share,but also to provide people with relevant network services through it.Whether you are getting the information you want or enjoying the Internet service,you can use a browser to access the website.In addition to completing the course,it is also important for students to attend the third class.The status quo is that teachers need excellent students to participate in their spare time for scientific research.Students who have the ability to learn,also hope that they can learn more information and join the teacher's team.Now to solve this problem is basically by the counselor to draw two groups between teachers and students,instructors to collect information about subject,side of the teacher let students look to whether have intention to join the teacher team,this is both time-consuming and inefficient.There is no such public platform for mutual selection between the two groups.This article will through the MySQL database on the Internet,the PHP language,Apache server design and build a dynamic platform for the teachers and students to elect,to teachers and students to provide a convenient and reliable two-way choice way.Based on the university teachers and students as the object,on the basis of requirement analysis to the actual inspection,the university teachers and students was designed and implemented a can publish individual performance and demand information between teachers and students,and online learning,online examination system.On the one hand,the system collects and integrates the scientific research situation of teachers(such as project,academic report,etc.)for a long time,so that students can understand the scientific research strength of teachers.On the other hand,students' learning status of basic courses and professional courses(such as grades)will be collected,and students who are interested in joining the teacher team will be assessed and selected.The specific content is embodied in the following aspects: 1.The system is divided into front end and back end,the front end is the interface presented to users,and the back end includes business logic processing and database.Second,through phpMyAdmin(MySQL database management tools)to establish a database,create multiple database,the system needs to function in the form of module partition,convenient for management,but also benefit for the development and maintenance of the platform.CSS is a standard way to format a web page,according to which the browser knows how to display elements and their contents.4.Use ECharts(JavaScript chart library)to display the number of teachers and students' achievements(such as how many patents a teacher has obtained).5.Through the use of PHP forms,teachers and students can log in,teachers arrange assessment,and students online assessment.Six,by setting the SESSION variable into the way of the teachers and students their own system,each teacher has his own assessment tasks,after students online examination to select different teachers arrangement by teachers to do the corresponding assessment tasks and view the scores.The core of the teacher-student mutual selection platform designed in this paper is database(background)and scientific display(front end)of data.Research progress,academic reports,papers,competitions and other academic activities are stored in well-designed backstage databases.This platform has also designed many practical data integration and presentation methods(including detailed tables and vivid graphics,etc.)to facilitate teachers and students to quickly,efficiently and accurately obtain the required information.At the same time,the maintenance of the platform is convenient.When an innovation activity occurs,the administrator only needs to add a record in the database,and the front page will be updated automatically with low maintenance cost.
