Modernize Outdated PHP & Security Hardening
Outdated PHP codebases (PHP 5.x/7.x) pose severe security risks, SQL injection vulnerabilities, and performance bottlenecks. My Legacy Code Refactoring service migrates old procedural code to modern PHP 8.x standards with clean MVC patterns and security audits.

PHP 8.x Upgrade
Fix deprecated functions, type declarations, and strict error handling.
SQL Injection Hardening
Replace unsafe SQL queries with PDO prepared statements and parameter binding.
Database Query Tuning
Index optimization, slow query fixes, and MySQL table restructuring.
