Abstract	SQL Injection (SQLi) remains one of the most critical and persistent security vulnerabilities affecting web applications worldwide. This research paper presents a comprehensive analysis of SQL Injection attacks, their underlying mechanisms, various attack categories, and the most effective prevention strategies available to developers and security professionals. Through the design and testing of both vulnerable and secured application modules built using PHP and MySQL, this study empirically demonstrates the impact of SQLi attacks and validates the effectiveness of mitigation techniques including parameterized queries, prepared statements, input validation, and least-privilege database access. Results confirm that properly implemented prevention measures can completely neutralize common SQLi attack vectors.
