PHP-based college student attendance and leave management system
The college student leave and attendance system is based on the php programming language and mysql database development. The system is divided into three roles: students, teachers, and administrators. Students can log in to the system, modify personal information, check attendance leave records, and apply for leave online. Teachers can Log in to the system to manage student information, view student leave, review information, and apply for leave information yourself; the administrator manages student information, teacher information, administrator information, and leave application information. This system is fully functional and has papers, which is suitable for learning as a reference for php graduation design.
