SQL Injection Practice Lab (PHP + MySQL)

This repository contains a deliberately vulnerable PHP application created for educational purposes to practice and understand SQL Injection (SQLi) techniques.

The project demonstrates common SQL injection scenarios, including:

• Classic SQL Injection
• Limit-based behavior
• Basic keyword filtering (ineffective by design)
• Input handling flaws

⚠️ This application is intentionally insecure. Do NOT deploy in production environments.
