PHP Website Development Agency in India for New Builds and Rescued Ones

Most PHP work in India is not a new build. It is a system that still runs the business, was written years ago by someone nobody can reach, sits on an unsupported PHP version and has no documentation. We do both jobs — modern PHP development for new projects, and the unglamorous work of modernising what the last developer left behind.

Overview

The Risk Is Not That Your PHP Site Is Old. It Is That Nobody Can Touch It.

The pattern is familiar in every industry we work with. A custom PHP application was built six or eight years ago, it works, and it quietly became the system the business depends on. Then the original developer moves on. There is no documentation, no repository, no staging copy — just files on a cPanel shared hosting account, edited directly over FTP. Nobody dares change anything, so nothing gets changed, and the risk compounds silently.

Underneath, the problems are specific and fixable. Deprecated functions that stop the code running on PHP 8. Old mysql_ calls instead of PDO or MySQLi with prepared statements, which is how SQL injection gets in. Passwords stored as md5 hashes rather than bcrypt or Argon2. No input validation on file uploads, no CSRF tokens, no escaping against XSS. Business logic and SQL queries written straight into template files — spaghetti code that works until somebody needs it to do something new.

Our first move is never a rewrite. We run a code and security audit, get the application into Git, set up a staging copy and automated backups, and fix the things that could cost you this month — the OWASP basics, the slow queries, the missing indexes. Only then do we modernise, and usually incrementally: PHP 8 compatibility, Composer and autoloading, PSR-12 coding standards, an MVC structure introduced module by module while the live system keeps running.

For new projects we are frank about one thing. Bespoke core PHP with no framework looks cheaper on the quote and costs more over five years, because routing, validation, authentication and security all get reinvented and none of it is documented. Unless there is a real constraint, we build on CodeIgniter, Symfony or Laravel — proven structure, faster delivery, and any PHP developer can pick it up after us.

What We Do

Six workstreams in PHP development services. A rescue project usually starts with three; a full modernisation uses all six.

Custom PHP Web Development

New custom PHP web development built on CodeIgniter, Symfony or Laravel rather than bespoke core PHP — business portals, booking systems, admin panels and PHP eCommerce, with role management and clean database design.

Legacy PHP Modernisation & Refactoring

Spaghetti code untangled into an MVC structure module by module, Composer and autoloading introduced, PSR-12 standards applied and technical debt paid down — without taking the live system offline for months.

PHP Version Upgrades & Hosting Migration

PHP 7.4 and earlier moved to PHP 8 — deprecated functions replaced, compatibility tested on staging first — plus migration from shared cPanel hosting to a properly configured VPS with Apache or Nginx, OPcache and SSL.

Security Hardening, Bug Fixing & Recovery

mysql_ calls replaced with PDO and prepared statements, md5 passwords rehashed to bcrypt or Argon2, CSRF tokens, XSS escaping and file upload validation added — plus malware cleanup and recovery for compromised applications.

PHP API Development & Integrations

REST API development returning clean JSON, plus integration with payment gateways including Razorpay, PayU and CCAvenue, SMS and email providers, Tally and ERP systems, invoice and PDF generation and scheduled cron jobs.

Maintenance, AMC & Dedicated PHP Developers

Monthly PHP maintenance covering patches, backups, uptime monitoring, error log review, slow query checks and a defined response time — or hire dedicated PHP developers from our team to work alongside yours.

Who it's for

PHP Development for Businesses With Systems That Must Keep Running

Businesses with an inherited PHP system

The application that runs orders, admissions or inventory, built years ago by someone no longer reachable. We document it, secure it and make it safe to change again.

Companies stuck on an old PHP version

Hosting has flagged PHP 7.4 as end of life, the host is forcing an upgrade, and the code breaks on PHP 8. We fix compatibility on staging before anything touches production.

Organisations needing custom internal tools

Approval workflows, dealer and vendor portals, reporting dashboards and internal systems where a CMS does not fit and a full product build is more than the job needs.

Agencies and product teams

A reliable PHP backend partner for client work or overflow capacity — under NDA, white-label where needed, working inside your repository and your process.

Told you need a complete rewrite? Get a second opinion first. Refactoring an application in stages is often half the cost and carries a fraction of the risk.

How It Works

How We Approach a PHP Project

01

Code & Security Audit

We read the codebase, check the PHP version, database schema, error logs and hosting setup, and test for the OWASP basics — SQL injection, XSS, CSRF, file upload and session handling. You get the risk list whether or not you proceed.

02

Stabilise Before Changing Anything

Automated backups, a staging copy and Git version control put in place, credentials secured, and the urgent security holes patched — so the system is safe to work on before anyone starts improving it.

03

Upgrade, Refactor or Build

PHP 8 compatibility, Composer and autoloading, query optimisation with proper indexes, and MVC structure introduced module by module — or, for new projects, a framework build in two-week sprints with code review.

04

Harden, Document & Maintain

SSL, server hardening, uptime monitoring and error tracking configured, technical documentation and code comments written, your team trained, then monthly AMC with a defined response time.

Why us

Why "Core PHP" Is Usually a Saving That Costs You Later

Bespoke core PHP wins the quote comparison. Five years on it is the most expensive line in the budget. Routing, validation, authentication, session handling and security were all written from scratch by one person, in their own style, with no documentation and no tests. Every new developer who looks at it quotes more to understand it than it cost to build, and the honest ones recommend a rewrite — which is how businesses end up paying twice for the same system.

We would rather you did not. On new projects we build on a framework so the structure is familiar to any PHP developer who follows us. On inherited projects we stabilise first and modernise in stages, keeping the application live throughout, and we write the documentation that was never there. The repository, the hosting, the domain and the database are yours from day one — our value is that you can replace us, not that you cannot.

Questions

FAQs

A custom PHP web application on a framework typically runs ₹1.5 lakh to ₹6 lakh depending on roles, workflows and integrations. Legacy modernisation and PHP 8 upgrades are quoted after the audit, usually between ₹40,000 and ₹2.5 lakh depending on codebase size and how much security work it needs.

Yes — that is a large part of our work. We read the codebase, map what it does, get it into Git with backups and a staging copy, and document it as we go. You do not need the original developer, only access to the hosting, domain and database.

It can, which is exactly why it is done on staging first. Deprecated functions and removed features are identified, fixed and tested against real data before anything reaches production. Done properly, the live switch is a few minutes of downtime at most.

For anything beyond a small script, use a framework. CodeIgniter, Symfony or Laravel give you tested routing, validation, authentication and security for free, and any PHP developer can continue the work. Bespoke core PHP saves money on the quote and costs it back in maintenance.

Refactor, unless the data model itself is beyond saving. Rewrites are expensive, slow and risky because nobody documented what the old system actually does. Our audit tells you plainly which one your codebase justifies, with a cost for each.

Yes. After stabilising the project with backups, staging and version control, we work module by module — bug fixing, new features and query optimisation — while the application stays live for your users.

You do. The repository, hosting account, domain and database are all in your name, and we work as collaborators inside them. Documentation is written so another PHP developer can take over without a discovery project.

Both. AMC covers patches, backups, uptime monitoring, error log review and a defined response time for issues. If you need steady capacity instead, you can hire dedicated PHP developers from our team on a monthly basis.
