Technical Evaluation Framework: Vetting CodeIgniter Development Agencies

CodeIgniter is a lightweight, low-footprint PHP framework. Evaluating CodeIgniter partners requires assessing whether they follow modern CodeIgniter 4 architecture or cling to outdated practices.

1. CodeIgniter Framework Capabilities

• ▸
  CodeIgniter 4 Modern Architecture: Full adoption of CodeIgniter 4 with PSR compliance, namespaces, MVC architecture, and modern PHP 8 compatibility.
• ▸
  Lightweight Performance Tuning: Leveraging CodeIgniter's minimal server footprint, fast execution times, and custom caching layers.
• ▸
  Security & Input Filtering: Applying built-in CSRF protection, XSS filtering, secure query binding, and input validation.

2. Buyer Diligence & Vetting Criteria

1. ▸
   Legacy CodeIgniter 3 Migration Strategy: Concrete roadmaps for modernizing legacy CodeIgniter 2/3 applications to version 4 or modern frameworks.
2. ▸
   Clean MVC Separation: Enforcing strict separation between Controllers, Models, and Views without inline business logic in templates.
3. ▸
   Database Layer Discipline: Utilizing Query Builder safely, adding database indexes, and avoiding raw SQL injection vectors.

3. Red Flags to Watch For

• ▸
  Maintaining Unsupported CodeIgniter 3: Refusing to upgrade deprecated CodeIgniter versions that lack modern security patches and PHP 8 support.
• ▸
  Direct Database Queries in Views: Blending database logic directly into view files, producing unmaintainable legacy code.
• ▸
  Absence of Version Control & Modern CI/CD: Deploying CodeIgniter applications manually via FTP rather than automated git pipelines.
