Technical Evaluation Framework: Vetting Modern PHP Development Agencies

Modern PHP is a fast, typed, and enterprise-ready language powering modern web applications. Buyers must differentiate legacy procedural coders from modern PHP engineers.

1. Modern PHP Ecosystem & Architecture

• ▸
  PHP 8.x Modernization: Leveraging strict typing, attributes, constructor property promotion, enums, match expressions, and JIT compilation.
• ▸
  Framework Leadership: Production mastery of Laravel (Eloquent, Queues, Horizon) or Symfony (Components, Bundles, Messenger) frameworks.
• ▸
  High-Performance Runtimes: Experience configuring PHP-FPM, OPCache, and asynchronous application servers like RoadRunner or Swoole.

2. Buyer Diligence & Vetting Criteria

1. ▸
   PSR Standards & Tooling: Adherence to PHP-FIG standards (PSR-12 code style, PSR-4 autoloading) and static analysis tools (PHPStan, Psalm at strict levels).
2. ▸
   Automated Testing Culture: Comprehensive testing using PHPUnit or Pest, testing both business domain logic and HTTP API endpoints.
3. ▸
   Database Architecture & Caching: Redis caching patterns, database indexing, queue workers, and horizontal scaling strategies.

3. Red Flags to Watch For

• ▸
  Legacy Procedural Code Habits: Mixing business logic directly into template views, using global variables, or disabling strict typing (declare(strict_types=1)).
• ▸
  Ignoring Dependency Management: Manually managing external libraries without Composer or neglecting security vulnerability scanning.
• ▸
  Lack of ORM Optimization: Causing severe database performance bottlenecks through unindexed queries and unoptimized relational loading.
