PHP2Shell went public on 21 October 2026: two critical flaws in PHP that can let an attacker run code on your server without signing in. A new React front end alone does not fix it, because your PHP back end still runs, and PHP below 8.2 gets no patch. Don't worry: in 7 days we move your screens to React and put the back end on a fixed PHP 8.4 release. See how the PHP update works.
Our PHP to React migration services in USA and UK companies replace the part of your app users see: the PHP templates, the jQuery and the full-page reloads. Your business logic and database usually stay where they are. We turn the PHP side into a clean JSON API and build a React front end that talks to it.
This suits customer portals, dashboards, admin panels and SaaS screens, where people log in and click around for a long time. We build with React and TypeScript on Vite, handle routes with React Router, fetch and cache server data with TanStack Query, and build forms with React Hook Form. The PHP endpoints are cleaned up, secured with tokens or same-site cookies, and moved to PHP 8.4.
Our team in Gujarat, India brings more than a decade of web development. We work hours that touch the US Eastern day and UK business hours, and we send a short demo video of progress each day.
Why swap PHP templates for React
Server-rendered PHP pages work, but every click means a full reload and every new feature means more tangled template code. React splits the screen into small, testable parts.
App-like screens
Tables filter, forms validate and panels update without reloading the page, so busy users get through their work faster.
Reusable components
A button, a date picker or an order table is built once and used everywhere, which keeps the look consistent and changes cheap.
Front and back end split cleanly
With a JSON API in the middle, front-end and back-end developers can work in parallel, and a mobile app can use the same API later.
What our React front-end migration covers
- Every PHP template rebuilt as React components in TypeScript
- PHP pages turned into JSON API endpoints, upgraded to PHP 8.4
- Login moved to secure cookies or tokens, existing accounts kept
- Routing with React Router, data loading with TanStack Query
- Forms and validation with React Hook Form
- Your design system or Tailwind CSS styling
- Component tests with Vitest and React Testing Library
- Build and hosting on your server, a CDN or a static host
From PHP templates to React in 7 days
Day 1: Screen inventory
We list every page and form, note the data each one needs, design the API shape, and agree the scope and fixed price.
Days 2-4: API and components
PHP endpoints return JSON on PHP 8.4 while the React app takes shape screen by screen with shared components.
Days 5-6: Click-through testing
We test every flow in major browsers and on mobile, compare results with the old pages, and you review on staging.
Day 7: Switch the front end
The React build goes live on your domain, old template routes are retired, and we watch errors in the browser and API.
PHP-rendered pages vs React front end
What users and developers notice after the change.
| PHP templates | React with a PHP API | |
|---|---|---|
| Navigation | Full page reload on every click | Instant view changes in the browser |
| UI code | HTML, PHP and jQuery mixed in one file | Typed components with their own tests |
| Data | Queried inside the template | Fetched from a JSON API and cached |
| Mobile app | Needs its own back end | Can reuse the same API |
| Public page SEO | Good, HTML comes from the server | Weaker for client-only pages, so we use Next.js where it matters |
| Hiring | Fewer front-end developers want PHP templates | React is the most common front-end skill |
Why use us for a React migration
We handle both ends of this job, so the API and the screens fit together on day one.
We fix the back end too
Most React agencies leave your old PHP alone. We clean the endpoints, close obvious security gaps and upgrade PHP so the new front end sits on a safe base.
One fixed price for front end and API, agreed after a free audit.
NDA signed before you share code or test accounts.
React migration for USA and UK businesses
This service is aimed at SaaS firms, agencies and companies in the United States and the United Kingdom whose customers log into a dated PHP portal. Our working hours overlap US Eastern and UK time, and we answer messages the same day.
An offshore React team in India costs far less than local front-end contractors, works for a fixed price under NDA and gives you one point of contact through launch.

Frequently asked questions
Straight answers about our PHP to React Migration service.
Most small and medium apps get a React front end and a PHP 8.4 API in 7 days. Very large apps get a phased plan, where the most used screens go live within the same 7 days and the rest follow.
No. In most cases we keep your PHP logic and database, turn the pages into a JSON API and upgrade to PHP 8.4. A full back-end move is a separate choice.
A React app that renders only in the browser is weaker for public pages that must rank. For marketing pages and blogs we suggest Next.js, and keep plain React for logged-in screens.
Not by itself, since the API still runs on PHP. That is why every React project we do includes moving the back end to a patched PHP 8.4 build.
Yes. React can take over one area, such as the dashboard, while the rest of the site stays on PHP templates until its turn comes.
Yes. We hold calls within US Eastern and UK hours, reply the same day, sign an NDA and agree a fixed price up front.
