PHP2Shell, two critical PHP flaws (CVSS 9.2), went public with its fix on October 21, 2026, four days after an exploit attempt was recorded. New React screens alone leave the risk in place, because your PHP back end still runs. The plan moves your screens to React and the back end to patched PHP 8.4.27, and most small and mid-sized apps move in 7 days. See how the PHP update works.
PHP to React migration services replace the part of your app that users see: PHP templates, jQuery and full-page reloads. Your business logic and database usually stay where they are. US teams end up with a clean JSON API on the PHP side and a React front end that talks to it.
React fits customer portals, dashboards, admin panels and SaaS screens, where people log in and click around for a long time. The stack is React and TypeScript on Vite, React Router for routes, TanStack Query to fetch and cache server data, and React Hook Form for forms. PHP endpoints are cleaned up, secured with tokens or same-site cookies, and moved to PHP 8.4.

Why swap PHP templates for React
React splits the screen into small, testable parts. Server-rendered PHP pages work, but every click means a full reload and every new feature adds tangled template code.
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, date picker or order table is built once and reused, so the look stays consistent and one edit updates every screen.
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
Every page and form is listed with the data it needs, then the API shape is drafted and you agree scope and 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
Each flow is tested in major browsers and on mobile against the old pages, and you review it all on staging.
Day 7: Switch the front end
The React build goes live on your domain, old template routes are retired, and developers track browser and API errors.
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
One team handles both ends of the job, so the API and screens fit together from day one.
Back end fixed as well
Developers clean the PHP endpoints, close obvious security gaps and upgrade PHP, so the new front end sits on a patched base.
One quote covers screens and API, fixed once the audit is done.
NDA available before you share code or test logins.
React migration for US businesses

Frequently asked questions
Straight answers about our PHP to React Migration service.
Most small and mid-sized apps get React screens and a PHP 8.4 API in 7 days. Large apps get a phased plan that starts with the most used screens.
No. In most cases your PHP logic and database stay, the pages become API endpoints, and the server moves to PHP 8.4. A full back-end move is a separate choice.
For public pages, it can be. A browser-only React app is weaker for pages that must rank, so marketing pages and blogs go on Next.js and logged-in screens stay on React.
No, because the API still runs on PHP. Every React project in this service includes moving the back end to PHP 8.4.27, the patched 8.4 release.
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. US clients get calls in US Eastern hours and agree the fixed price up front, with an NDA if needed.
Is your PHP app still on an old version?
Send the URL or repository, under NDA if needed. The audit checks for the PHP2Shell flaw and outdated code and shows what a 7-day migration looks like.
