CodeIgniter Development & Upgrades
Your billing system or customer portal was built on CodeIgniter 3 years ago, it still does the job, and now the host wants you on PHP 8.2. Suddenly the logs fill with "Creation of dynamic property is deprecated" and some pages stop loading.

Why it matters
Why invest in CodeIgniter Development & Upgrades

Runs on Current PHP
The upgraded app works on PHP versions your host is not about to retire.
Small and Quick
CodeIgniter 4 suits simple, fast apps that do not need a heavier framework.
What you get
What's included in CodeIgniter Development & Upgrades
We look after existing CodeIgniter apps and move older ones to CodeIgniter 4. Be aware that CI3 to CI4 is closer to rewriting the application layer than to an update. Controllers get namespaces, models and the Query Builder behave differently, routes are declared explicitly, and custom libraries and helpers need reworking. We plan it so your data stays put and your URLs keep working.
For a new project, CodeIgniter 4 is still a sensible pick when you want a small, quick framework without much overhead. Whatever the job, it goes through a staging copy, Git and a full backup before anything is deployed.
- Code AuditCI version, custom libraries, third-party code and PHP compatibility checked and written up.
- CI3 to CI4 MigrationControllers, models, routes and config rewritten into the CodeIgniter 4 structure.
- Data and URLs KeptExisting tables and URL patterns preserved, with 301 redirects wherever a route has to change.
- New FeaturesReports, user roles, APIs or integrations added to the app you have now.
- Security FixesCSRF protection switched on, query bindings used throughout and output escaped properly.
- Staged DeploymentTested on a staging copy first, then deployed with a rollback plan ready.

FAQ
Questions about CodeIgniter Development & Upgrades
Can't find your answer? Call us on +91 99995 89261.
Is upgrading from CodeIgniter 3 worth it?
If the app matters to your business, yes. CodeIgniter 3 is in maintenance mode and older releases struggle on newer PHP.
Will the upgrade mean downtime?
Usually only a short planned window. We build and test the new version on staging, then switch over.
Should we just move to Laravel?
Sometimes, for larger apps. We can price a CI4 migration and a Laravel rebuild side by side before you decide.
Do you still work on CodeIgniter 2?
Yes. Apps that old usually need a careful upgrade path first, because they depend on PHP features that no longer exist.
