## Overview

This is a small PHP internship-management application. Users submit credentials, which are checked against the users table; successful login stores the user in the session and routes admins to the stage overview or students to their own stage dashboard. Admin review and student viewing are distinct workflows. The supplied admin page offers validation/rejection forms, but their target handler is absent from the tree; the entreprise, etudiants and stages files are empty in the supplied excerpts, so their behavior cannot be mapped.

Main entry points: [`public/login.php`](https://github.com/misterizraiah/gestion-stages-php/blob/main/public/login.php) (Sign in), [`public/admin.php`](https://github.com/misterizraiah/gestion-stages-php/blob/main/public/admin.php) (Admin overview), [`public/dashboard.php`](https://github.com/misterizraiah/gestion-stages-php/blob/main/public/dashboard.php) (Student dashboard), [`public/logout.php`](https://github.com/misterizraiah/gestion-stages-php/blob/main/public/logout.php) (Sign out)
