## Overview

This PHP student-management application lets students retrieve a record by standard and roll number, while authenticated admins can insert, search for, update, and delete records. The public lookup is handled by the homepage and a helper; admin workflows use separate pages and MySQL-backed records. The README documents the MySQL database and CRUD capabilities. The update submission handler is present in the tree but was not excerpted, so its database behavior is not asserted.

Main entry points: [`dbcon.php`](https://github.com/diveshlunker/management-system-students/blob/master/dbcon.php) (MySQL Connection), [`Admin/admindash.php`](https://github.com/diveshlunker/management-system-students/blob/master/Admin/admindash.php) (Admin Dashboard), [`login.php`](https://github.com/diveshlunker/management-system-students/blob/master/login.php) (Admin Login), [`Admin/addstudent.php`](https://github.com/diveshlunker/management-system-students/blob/master/Admin/addstudent.php) (Add Student)
