PHP Development Services for Web and Enterprise Applications
Citrusbug delivers PHP development services that cover the full application lifecycle. Each engagement starts with architecture decisions and framework selection, and ends with deployment, monitoring, and post-launch support.
Custom PHP Web Applications
Custom PHP applications covering frontend experiences and backend development, with architecture designed around your business workflows, integrations, and data requirements. Built on Laravel or Symfony with production-ready CI/CD pipelines.
PHP API Development and Integration
RESTful and GraphQL API layers that connect your PHP application to payment gateways, CRMs, ERPs, and third-party data sources. Authentication through OAuth 2.0 and JWT with rate limiting and versioned endpoints.
PHP CMS and Portal Development
Content management systems and client portals built on custom PHP or extended from WordPress and Drupal. Multi-tenant architecture, role-based content workflows, and headless CMS configurations for decoupled front ends.
Enterprise PHP Application Development
Large-scale PHP platforms for organizations managing complex workflows, multi-location operations, or high-transaction volumes. Horizontal scaling through PHP microservices, queue-based processing, and containerized deployments.
Legacy PHP Modernization and Migration
PHP 5.x and 7.x applications upgraded to PHP 8.4/8.5 with framework migration (Zend to Laminas, CodeIgniter 3 to 4, custom MVC to Laravel). Includes dependency audit, automated test coverage, and staged rollout.
PHP Microservices Architecture
Monolithic PHP applications decomposed into independently deployable services using RoadRunner or PHP-FPM with Nginx. Each service owns its data store, communicates through message queues, and scales without affecting the rest of the platform.
PHP Code Audit and Performance Optimization
Existing PHP codebases reviewed for security vulnerabilities (SQL injection, XSS, CSRF), performance bottlenecks (N+1 queries, missing indexes), and architectural debt. Deliverables include a prioritized remediation roadmap and estimated effort.
PHP Consulting and Architecture Design
Technical advisory for teams evaluating PHP frameworks, planning migrations, or designing multi-service architectures. Citrusbug engineers work alongside your team during discovery to define the stack, data model, and deployment strategy before any code is written.

Get a Technical ReviewPHP Project Risks to Address Before Development
PHP applications stall when architecture decisions get made late, when frameworks get chosen based on team familiarity rather than project fit, or when integrations with existing systems are treated as an afterthought. The cost of these mistakes shows up months into the build, when refactoring a poorly structured codebase becomes more expensive than the original estimate.
Citrusbug starts every PHP engagement with a discovery phase that documents requirements, maps integration points, and selects the framework and infrastructure before a single line of production code is written. The goal is to catch the decisions that would otherwise surface as blockers during sprint three or four.

Laravel handles rapid prototyping and convention-based routing well. Symfony fits enterprise applications with complex dependency injection and long-term maintainability requirements. Picking the wrong one adds refactoring cost later.
Payment processors, ERP connectors, CRM sync layers, and SSO providers each carry their own authentication and data format requirements. Documenting these during discovery prevents blocked sprints.
Query patterns, indexing strategy, and read/write separation planned against realistic traffic projections. Migration scripts version-controlled from day one.

PHP Frameworks and Tools We Use in Production
Citrusbug selects the PHP framework and supporting tools based on application requirements, existing team expertise, integration needs, and long-term maintainability. Production environments use modern PHP versions with Composer for dependency management, PHPStan for static analysis, and containerized workflows for consistent development, staging, and deployment.
-
Laravel 11 for convention-driven web applications and APIs
-
Symfony 7 for complex enterprise applications and modular architectures
-
CodeIgniter 4 for lightweight applications and services
-
MySQL and PostgreSQL for transactional and relational data workloads
-
Docker and GitHub Actions for containerized development and CI/CD
PHP DEVELOPMENT PROCESS
How We Deliver PHP Development Projects
01
Discovery and Scoping
Requirements documented, integration points mapped, framework selected, and architecture designed. Deliverable: technical specification and project plan with estimated timeline.
02
Environment and CI Setup
Development, staging, and production environments provisioned with Docker. CI/CD pipeline configured with automated linting, PHPStan analysis, and test execution on every push.
03
Iterative Development
Two-week sprints with working deployments at the end of each cycle. Code reviews on every pull request. Progress tracked through shared project boards with daily async updates.
04
QA and Security Testing
Functional testing, load testing against projected traffic, and security audit covering OWASP Top 10 vulnerabilities. Automated regression suite built alongside features.
05
Deployment and Handover
Production deployment with zero-downtime release strategy. Full source code ownership transferred. Documentation covers architecture decisions, environment setup, and operational runbooks.
PHP Migration and Modernization Services
Upgrading from PHP 7.x to 8.5
PHP 7.4 reached end of life in November 2022. Applications still running on 7.x are exposed to unpatched vulnerabilities and cannot use typed properties, union types, named arguments, or JIT compilation. Citrusbug handles the full migration, including dependency compatibility checks, deprecation fixes, and staged rollout with parallel testing.
Framework Migration Without Rebuilding
Moving from Zend Framework to Laminas, CodeIgniter 3 to 4, or a custom MVC to Laravel does not always require a ground-up rewrite. Citrusbug identifies which modules can be migrated incrementally and which need replacement, keeping the application running throughout the transition.
Monolith to Microservices Transition
PHP monoliths that have grown past their architectural limits benefit from selective decomposition. Citrusbug extracts high-load or frequently changed modules into standalone services while keeping the rest of the application stable, using message queues and API contracts to maintain data consistency.

Stalled Project Recovery
PHP projects handed off mid-build by a previous team or abandoned due to technical debt are recoverable. Citrusbug takes over inherited codebases, conducts a code audit, stabilizes the existing build, and resumes development from a clean baseline with updated documentation.

Enterprise PHP Architecture and Modernization Services
Architecture-First Planning
Enterprise PHP applications fail when teams skip architecture review and move straight to coding. Citrusbug provides custom software development consulting that defines the data model, service boundaries, and deployment topology before build begins. This prevents the mid-project rewrites that inflate enterprise project budgets.
- Technology selection (Laravel vs Symfony vs custom)
- Multi-database strategy and caching layer design
- API contract definitions for front-end and mobile consumers
- Infrastructure sizing and auto-scaling configuration
Outcome:
A documented architecture that the engineering team can execute against with confidence.
Legacy PHP Application Rescue
Applications built on PHP 5.x or early 7.x with accumulated technical debt, missing tests, and undocumented dependencies are a common challenge for enterprise teams. Citrusbug takes over these legacy applications with a structured audit-stabilize-modernize approach. The codebase is brought to PHP 8.4/8.5 compatibility while preserving business logic the organization depends on.
- Code audit with vulnerability and performance assessment
- Test harness built around critical paths before any changes
- Incremental framework upgrade without service interruption
- Post-modernization documentation and team training
Outcome:
A maintainable, secure codebase running on supported PHP versions with automated test coverage.
