CodeIgniter 4 is a lightweight, full-stack PHP web framework with a small footprint, MVC architecture, and built-in security features like CSRF and XSS protection. It is a modern rewrite of the classic CodeIgniter framework, targeting PHP 8.1+ with near-zero configuration and clear documentation.

Use cases

• build a full-featured web application in PHP
• create a REST API with routing and controllers
• build an MVC web app with a small framework footprint
• develop a database-driven website with query builder and migrations
• learn PHP web development with a simple framework
• build a lightweight website with built-in CSRF and XSS protection

When to choose

• you want a fast, lightweight PHP framework with minimal configuration
• you prefer simple, elegant tooling over heavy complexity
• you need built-in security features and clear documentation
• you want a framework that encourages but doesn't force MVC

When to avoid

• you need a large ecosystem with extensive third-party packages like Laravel's
• you want async or event-driven architecture
• your team prefers heavily opinionated, convention-over-configuration frameworks
• you are maintaining a legacy PHP 5.6 project (use CodeIgniter 3 instead)
