PHP still runs a disproportionate share of the enterprise web — customer portals, broker extranets, policy servicing screens, agent onboarding flows, admin consoles bolted onto core systems. Our practice is built around keeping that surface area fast, testable and safe to change, whether we are writing a new Laravel service or untangling a decade-old codebase that has outlived three CTOs.
What we build in PHP
Most of our PHP work falls into three shapes. The first is greenfield application development on Laravel — customer-facing portals, partner dashboards, quote-and-buy journeys, claims intake, KYC and onboarding front-ends that sit in front of a policy admin system or a core banking stack. Laravel gives us Eloquent, queues, Horizon, Sanctum/Passport for token issuance, Livewire or Inertia where a full SPA is overkill, and Filament for internal admin surfaces.
The second is Symfony work, usually where the domain model is heavier and we want Doctrine, the Messenger component and a stricter hexagonal layout — pricing engines, rating tables, commission calculators, document generation services, integrations that need to survive audit. Symfony bundles also show up when we are extending existing platforms — Sylius for commerce, API Platform for spec-first REST/GraphQL, EasyAdmin for back office.
The third is legacy modernisation — CodeIgniter 2/3, Zend 1, Yii 1, CakePHP 2, WordPress installs that grew into applications, and hand-rolled PHP 5 codebases still in production. We stabilise these, put them behind tests, upgrade the runtime, and either migrate incrementally onto a modern framework or wrap them behind a new API while the strangler-fig runs.
Engineering baseline
Every PHP engagement starts from the same floor. PHP 8.3+ with strict types, readonly properties, enums and first-class callable syntax used deliberately, not decoratively. PSR-12 coding standard enforced by PHP-CS-Fixer or Pint. PHPStan at level 8 (or Psalm where the team prefers it) wired into CI so type regressions fail the build. Pest or PHPUnit for unit and feature tests, with Mockery or Prophecy for doubles and a real database in a container for integration tests — no SQLite-in-memory shortcuts when the target is PostgreSQL or MySQL.
Runtime is PHP-FPM behind Nginx, or RoadRunner / FrankenPHP / Swoole where the workload justifies a long-lived worker model (websocket fan-out, high-throughput APIs, event consumers). Composer 2, autoloader optimised, OPcache and JIT tuned per workload, preload.php used where it earns its keep.
Data layer is PostgreSQL or MySQL 8 with proper migrations, foreign keys and indexes reviewed on every PR that touches schema. Redis for cache, sessions, rate limits and queue transport. Laravel Horizon or Symfony Messenger with a Redis or RabbitMQ backend for background work — reminders, webhook delivery, PDF and statement generation, third-party API calls that must not block the request cycle. Meilisearch, Elasticsearch or Typesense for search when LIKE '%…%' stops being honest.
Observability is non-negotiable — structured JSON logging via Monolog, request IDs propagated across services, OpenTelemetry traces to Jaeger/Tempo/Datadog, Sentry for error capture, and health/readiness endpoints wired into whatever orchestrator is running the pods.
Where PHP fits in our BFSI and enterprise work
In our BFSI practice PHP is rarely the system of record — that lives in the core banking or policy admin platform — but it is very often the channel layer. Customer web portals, agent and broker workbenches, IRDAI/NAICOM/IRA-facing reporting consoles, grievance and complaint intake, e-KYC/CKYC front-ends, aggregator plumbing, and the internal ops UIs that finance and compliance teams actually use every day.
That means PHP code we write regularly integrates with regulator-facing APIs, sanctions and PEP screening providers, payment gateways, credit bureau responses, NACH/UPI/ACH rails, and downstream cores over SOAP, ISO 20022, REST or file drops. Idempotency keys, retries with exponential backoff, dead-letter queues, replay tooling and reconciliation reports are treated as first-class requirements, not afterthoughts.
The same PHP layer often talks to our CRM & ERP implementation work — Zoho CRM/Creator, Odoo, SuiteCRM and Salesforce — either as the customer front door or as the middleware translating between the CRM and a policy or loan management system.
Modernising a legacy PHP estate
When we take over a legacy PHP codebase the first pass is diagnostic — a static analysis baseline with PHPStan/Psalm, a dependency audit, a Rector dry-run to see how far automated upgrades can carry us, and a review of what is actually exercised in production versus what is dead code. We characterise the system with tests before we refactor, not after.
From there the paths are well-worn. Rector handles the mechanical PHP 5 → 7 → 8 upgrades, deprecations, and framework version bumps. Anti-corruption layers and API façades let a new Laravel or Symfony service take over one bounded context at a time. Sessions, auth and file storage are decoupled from the framework so the runtime can move to containers. CI/CD (GitHub Actions, GitLab, Jenkins) replaces FTP deploys. Secrets move out of .env files on disk into a vault.
We do not do big-bang rewrites. Every modernisation ships behind feature flags, with the old and new paths running in parallel until traffic and reports agree.
Why teams pick Redian for PHP
We have shipped PHP into regulated environments for years — insurers, banks, NBFCs, brokers, government-adjacent portals — so the conversation about audit trails, data residency, encryption at rest, RBAC and segregation of duties is one we have already had many times. Our engineers are comfortable operating inside client SDLC, ITSM and change-advisory processes, and we deliver either as a delivery-owned squad or through IT staff augmentation embedded into your existing team.
Selected work is written up in case studies. If you have a Laravel or Symfony build coming up, or an older PHP application that needs to be brought back under control, get in touch and we will scope it honestly.
