## Overview

This PHP/MySQL college-event system lets students create profiles, browse event categories, and register for events; organizers manage event listings and coordinator details. The visible flow begins at the home page and links to event views, while profile creation and event creation write to the shared database. Admin pages and registered-event lookup read event and student-related records. The tree documents additional registration, login, deletion, and coordinator pages, but their internal wiring is not established by the sampled source, so uncertain links are omitted.

Main entry points: [`EventManagementSystems/adminPage.php`](https://github.com/bhavanag7/college-event-management-system/blob/master/EventManagementSystems/adminPage.php) (Event administration), [`EventManagementSystems/utils/header.php`](https://github.com/bhavanag7/college-event-management-system/blob/master/EventManagementSystems/utils/header.php) (Public navigation), [`EventManagementSystems/classes/db1.php`](https://github.com/bhavanag7/college-event-management-system/blob/master/EventManagementSystems/classes/db1.php) (Event database), [`EventManagementSystems/index.php`](https://github.com/bhavanag7/college-event-management-system/blob/master/EventManagementSystems/index.php) (Event home)
