PHP has a reputation problem that its capabilities do not deserve. PHP 8.x is a modern, fast language with JIT compilation, named arguments, fibers for async, typed properties, match expressions and first-class callable syntax. A well-written PHP application is highly maintainable, performant and cost-effective to host. The problem is not PHP — it is the volume of poorly written PHP code from the early 2000s that still runs on production servers today. At Chulbul Design, we write modern PHP using OOP principles, PSR standards and proper separation of concerns — whether we are building a custom application from scratch, extending an existing system, or rescuing a legacy codebase that has become unmaintainable. We work in both framework (Laravel, Symfony, CodeIgniter) and vanilla PHP contexts.
Custom PHP Web Applications — Built Clean, Maintained Easily
Custom PHP applications are the right choice when your business process does not fit neatly into an off-the-shelf product. We build custom PHP applications for business workflows that are unique to your industry: commission calculation engines for direct-selling companies, inventory management for SME manufacturers, tender management for government contractors, property management for real estate firms, booking and scheduling systems for service businesses. Every application is built with MVC separation, a proper routing layer, prepared statements (no SQL injection risk), password hashing, CSRF protection, session security and server-side input validation. The code follows PSR-12 coding standards and comes with PHPDoc comments so the next developer is not starting blind.
A Delhi logistics company: custom PHP TMS (transport management system) replaced 4 disconnected WhatsApp groups and 3 Excel sheets — proof of delivery via mobile now updates dispatch office in real time.
- PSR-12 standards, OOP architecture, clean codebase
- PDO with prepared statements — zero SQL injection risk
- CSRF, XSS and session security built in from day one
- Role-based access with fine-grained permission control
- PHPDoc comments and developer handoff documentation
Legacy PHP Rescue — Upgrade, Secure and Optimise Old Code
There are millions of PHP 5.x and PHP 7.x applications running Indian business operations right now — applications that work but are slow, insecure and impossible to extend. If you inherited a PHP application that runs your business but that nobody wants to touch because the code is unmaintainable, we can help. Our legacy PHP rescue service starts with a full code audit: security vulnerabilities (SQL injection, XSS, exposed credentials, file upload exploits), performance issues (N+1 queries, missing indexes, full table scans), and architectural problems (no separation of concerns, global state everywhere). We then migrate the application to PHP 8.x, introduce autoloading and Composer dependency management, fix all security issues and refactor the most critical parts of the codebase to be maintainable.
- PHP 5.x / 7.x to PHP 8.x migration
- Full security audit — SQL injection, XSS, file upload exploits
- Composer introduction and PSR-4 autoloading
- Query optimisation — indexes, N+1 fixes, caching layer
- Zero downtime migration with parallel-run testing
CMS & Platform Customisation — WordPress, Magento, OpenCart
Many Indian businesses run their website or store on a PHP-based CMS that they need customised beyond what themes and plugins can do. We write custom WordPress plugins, custom post types with admin meta boxes, custom WooCommerce payment gateways for Indian processors, custom Magento modules for GST compliance and Indian shipping carriers, and OpenCart modifications for B2B functionality like customer-specific pricing and minimum order values. When a plugin does not exist for what you need, we build it from scratch following the platform's native coding standards — no conflicts, no update breakage, no performance drag from poorly written hooks.
- Custom WordPress plugins — hooks, REST API, custom blocks
- Custom WooCommerce payment gateways for Indian PGs
- Magento 2 modules — GST, shipping, B2B pricing
- OpenCart customisation — customer pricing tiers, bulk orders
- PHP cron jobs, CLI scripts and automated reporting

Full security review of existing PHP applications — SQL injection, XSS, CSRF, file upload vulnerabilities, exposed credentials, insecure session handling and dependency CVEs.
PHP Cron Jobs & Automation
Scheduled PHP scripts for data sync, report generation, payment reminders, inventory reconciliation, email/SMS dispatch and third-party API polling.
Our PHP Development Process
Scope & Specification
Every feature, user type, data flow and integration is documented in a written specification before any code is written — preventing scope creep and misaligned expectations.
Database & Architecture Design
Schema design, index planning and application architecture are defined before development begins so the foundation is solid and does not need to be rebuilt mid-project.
Development in Sprints
Built in 1–2 week sprints with staging demos. You test each sprint's output and give feedback before the next sprint starts — staying in control throughout.
Security & Performance Testing
OWASP Top 10 check, query profiling with EXPLAIN, load testing on critical paths, and code review for standards compliance before production deployment.
Deployment & Knowledge Transfer
Server setup, deployment documentation, code walkthrough with your team and a 30-day post-launch support period to catch any production-only issues.
