PHP Online Examination System

The Online Examination System is a web application developed in core PHP with a MySQL database that lets institutions conduct objective tests online. It has two roles: an admin who creates exams, adds questions and manages students, and a student who logs in to attempt scheduled exams.

Admins can create subjects, add multiple-choice questions with the correct answer, set exam duration and pass marks, and view detailed reports of every student attempt. Students see available exams, attempt them within a countdown timer, and receive instant results with score, percentage and pass/fail status. The system auto-evaluates answers and stores results for analytics.

Security features include session-based login, prepared statements to prevent SQL injection, and automatic submission when the timer ends. Bootstrap is used for a responsive interface. This is a classic, reliable academic project covering CRUD operations, authentication and reporting in PHP.

Detailed Project Description

PHP Online Examination System delivers questions, scores answers instantly and tracks progress so learners can practise and administrators can evaluate.

How It Works
1. Questions are stored with options, correct answers and categories.
2. A session presents questions one by one with a timer where required.
3. Answers are scored immediately and results saved per user.
4. Leaderboards / reports show performance over time.

Implementation Steps
1. Define requirements and draw the ER / class diagram and screen flow.
2. Set up the environment (XAMPP, PHP, MySQL) and create the project skeleton.
3. Design the database schema / data model and seed it with sample data.
4. Implement the core modules with validation and role-based access where needed.
5. Build the user interface and connect it to the backend / data layer.
6. Test each module (unit + manual), fix edge cases and secure inputs (SQL injection, XSS, auth).
7. Prepare documentation, screenshots and a demo build.

Key Features
- Question bank
- Timed sessions

Expected Output
On completion the student will have a scored result per attempt and a history of performance.

Deliverables
- Complete source code with comments
