A critical pair of bugs in PHP, together called PHP2Shell, was disclosed on 21 October 2026 with a CVSS score of 9.2. Amazon's threat team logged the first exploit attempt on 17 October, before any patch existed, and PHP 8.1 and older will never be fixed. Don't worry: we can move your app off PHP entirely and onto the MERN stack in 7 days. Read the full news report.
Our PHP to MERN stack migration services in USA and UK markets replace a PHP and MySQL application with MongoDB, Express, React and Node.js. The result is one language, JavaScript, from the database query to the button your customer clicks.
Most PHP apps we see split the work badly. Some logic lives in PHP, some in scattered jQuery, and the database schema has been patched with extra columns for years. In a MERN rebuild, React draws the interface from reusable components, Express serves a clean REST API, Node runs it, and MongoDB stores records as flexible documents that match the objects your code already passes around.
We have more than a decade of web development experience and a team in India that keeps US and UK business hours. You get a fixed price, a short daily update and a working MERN app at the end of the week.
What a single JavaScript stack gives you
The main draw of MERN is simplicity of people, not just code. One skill set covers the whole product, which matters when your team is small.
One language, one team
Front-end and back-end developers both write JavaScript, so the same person can fix a React screen and the Express route behind it.
Interactive screens
React's component model makes dashboards, live filters and multi-step forms far easier than PHP page reloads stitched together with jQuery.
Flexible records
MongoDB documents handle products with varying attributes or user profiles with optional fields without endless ALTER TABLE scripts.
Parts of your PHP app we rebuild
- Screens and forms rebuilt as React components
- PHP endpoints rewritten as Express routes and middleware
- MySQL tables mapped to MongoDB collections with Mongoose schemas
- Data export and import scripts, with row counts checked
- User accounts moved over with existing bcrypt hashes kept where possible
- JWT or session login, plus roles and permissions
- Payment, email and third-party API integrations
- Hosting on Node with PM2 or containers, SSL and backups
Our week-long MERN rebuild schedule
Day 1: Schema and scope
We study your tables and PHP files, design the MongoDB collections, agree the API list and confirm a fixed price.
Days 2-4: API and React build
Express routes and Mongoose models go in first, then the React screens are built against them, one module at a time.
Days 5-6: Data and testing
We run the data import, compare record counts and totals with MySQL, and test every flow with you on staging.
Day 7: Launch
A final delta import catches recent records, traffic moves to the Node app, and we stay on watch for errors.
PHP and MySQL vs the MERN stack
How the same business app changes layer by layer.
| PHP + MySQL | MERN | |
|---|---|---|
| Languages | PHP on the server, JavaScript in the browser | JavaScript (or TypeScript) everywhere |
| Data model | Fixed tables, joins and schema changes | Documents in MongoDB, shaped by Mongoose |
| Interface | Server pages reloaded on each click | React single-page app with reusable components |
| API | Often none, or ad hoc PHP scripts | Clear Express REST API ready for mobile apps |
| Real-time | Polling with AJAX | Node handles WebSockets with Socket.IO |
| PHP2Shell exposure | Depends on the PHP version installed | No PHP runtime left on the server |
Why our team for a MERN move
We read PHP fluently and write modern JavaScript daily, which is the exact mix a rewrite like this needs.
Data checked, not assumed
Moving from SQL to documents is where rewrites go wrong. We verify counts, totals and relations after every import run.
Price fixed after a free code audit, so the budget does not creep.
Your NDA is signed before any code or database dump changes hands.
MERN stack rebuilds for teams in the USA and UK
This service is built for growing companies in the United States and the United Kingdom that want to hire JavaScript developers for the whole product instead of keeping separate PHP and front-end people. We work hours that cross over with US Eastern time and the UK day, and we answer within the same day.
As an offshore team, we cost far less than a local agency for the same rewrite, and you still get a single contact, a written scope, an NDA and a launch date agreed up front.

Frequently asked questions
Straight answers about our PHP to MERN Stack Migration service.
Most small and medium PHP apps are rebuilt on MERN in 7 days: day one for schema and scope, three days of building, two days of data checks and testing, and launch on day seven. Very large apps get a phased plan with the first module live inside the same 7 days.
Not always. If your data is heavily relational, like accounting ledgers with many joins, we may suggest keeping a SQL database with Node and React instead. MongoDB pays off when records vary in shape or change often.
Usually not. PHP's password_hash produces bcrypt hashes by default, and Node libraries such as bcrypt can verify them, so users log in with the same password after the move.
Yes. The Express API we build is the same one a React Native or Flutter app would call, so adding mobile later does not mean another backend rewrite.
Once the old PHP app is switched off and removed from the server, the PHP2Shell flaws no longer apply to it. Node and npm packages then need their own regular updates, which we set up before handover.
Yes. We work with businesses in the USA and UK on their hours, with one project manager, a signed NDA, a fixed price and a short written update every working day.
