🚀 A modernized boilerplate for CodeIgniter 2 projects running on PHP 8.2/8.3+.This project patches the original CodeIgniter 2.2.6 core (system/ folder) to remove deprecated features, fix dynamic property issues, and update old MySQL calls for compatibility with modern PHP and MariaDB/MySQL.

## ✨ Features

✅ Fully compatible with PHP 8.2/8.3

✅ Dynamic properties declared (no more deprecation warnings)

✅ Replaced legacy mysql_* with mysqli

✅ Clean CodeIgniter 2.2.6 core ready for new projects

✅ Drop-in boilerplate for legacy CI2 apps that need to run today

✅ Works with MariaDB/MySQL 5.7+

## 📖 Why This Exists

CodeIgniter 2 was officially retired in 2015 and was never updated for PHP 7 or PHP 8.However, many developers still maintain or extend legacy CodeIgniter 2 applications.This repo provides a drop-in foundation so you can:

Build new projects with the lightweight CI2 framework on modern PHP

Upgrade old CI2 apps to run without errors on PHP 8+

Avoid fighting with deprecated features every time you set up a project

## 📂 Project Goals
