CodeIgniter

How it works

CodeIgniter handles incoming web requests and routes them to application code. Developers organize data access, page templates, and business rules within its structure. Built-in helpers cover recurring tasks such as validation and database queries, leaving the application to define its own features, permissions, and user experience.

What you can build

Build content management tools, customer portals, business applications, and APIs that connect websites to other services.

• Service request portal

  Accept customer forms, store their details in a database, and provide staff with a simple interface for reviewing and updating each request.

• Application integration API

  Expose selected business records through documented endpoints so a mobile app or partner service can exchange information with the underlying web application.

Things to consider

Framework versions and PHP requirements matter when maintaining older projects. Choose a supported setup and define validation, permissions, and database rules around the actual product.
