MotionLasers kept the Core PHP backend it already had. We restructured key parts, reworked the API responses behind the listing pages and added new features, and the store kept selling through the switch-over.
Our work
PHP applications we look after
A laser store whose Core PHP backend we kept and sped up, and a legal application on a legacy PHP and Yii stack that we maintain. Our Laravel projects are on the Laravel development page.

Core PHP backend · US
MotionLasers
A laser systems store in Austin, Texas. The Core PHP backend stayed: we restructured key parts, reworked its API responses and added features, under a new Next.js storefront. We still support it.

Legacy PHP maintenance · US
LFT (Law Firm Tools)
A legal application on a legacy PHP and Yii stack. We maintain it, ship updates and fixes, and are cleaning up its architecture so a move to PHP 8 can follow. Screens shown are illustrative.

What we do with PHP, from a new tool in plain PHP to legacy takeovers, version upgrades and the support behind them.
Book a free PHP consultation
-
Sites, portals and tools written in plain PHP, without a framework, when the job is small or your code already works that way.
-
Code another team wrote, read, kept running and cleaned up, so changes stop breaking other things.
-
PHP version upgrades
Older applications moved to a current PHP version step by step, with the clean-up and tests done first.
-
New builds on Laravel, and upkeep and upgrades for applications on CodeIgniter, Yii and CakePHP.
-
REST APIs from your PHP backend, and a faster Next.js or React front end on top of it.
-
Fixes, PHP and package updates and new features after launch, one change at a time.
Choosing a framework
Plain PHP, Laravel or another framework?
We work with all of them, so we have no reason to push you either way. This is how we help clients choose.
-
Choose plain PHP when
- The job is a small site, a form or a single script
- You already run core PHP code that works and is worth keeping
- Your hosting allows little more than PHP and a database
-
Choose Laravel when
- You are building a new application with accounts, roles and payments
- You need background jobs, queues and scheduled tasks
- You want code that many PHP developers can pick up later
-
Keep your framework if
- Your application already runs on CodeIgniter, Yii or CakePHP
- It works, and needs care and upgrades more than a rewrite
- A move to Laravel can wait until the code is in good shape
A PHP backend also pairs with a JavaScript front end: Next.js development and React development.
How we work
From first call to PHP you can change
Six steps, and the same way of working on every project, new code or old.
PHP development
What we build with PHP
New PHP, and the work that keeps older PHP fast, safe and easy to change. Where a project in our case studies shows it, the card links to it.
-
A new front end, the same PHP backend
MotionLasers kept its Core PHP backend; we reworked its APIs and put a Next.js storefront in front of it.
MotionLasers → -
Legacy application care
Updates and fixes for a legal application on a legacy PHP and Yii stack, keeping it working for its users.
LFT (Law Firm Tools) → -
Clean-up before an upgrade
The architecture reviewed and tidied first, so the planned move to PHP 8 can follow with features kept working.
LFT (Law Firm Tools) → -
Custom PHP tools and portals
Forms, portals and internal tools in plain PHP, written to be read and changed by the next developer.
-
REST APIs in PHP
APIs that your mobile app or JavaScript front end calls, with sign-in tokens, validation and versions.
-
New applications on Laravel
For a larger new build we usually reach for Laravel. Our Laravel projects are on their own page.

Why Provis
Why work with Provis on PHP
Six things you can check before you hire us.
-
We stay after launch
We still support the MotionLasers store and maintain the LFT application.
-
We keep what works
MotionLasers kept its Core PHP backend: restructured and extended, not started again.
-
Clean-up before upgrades
On LFT the architecture is being tidied first; the PHP 8 move comes once it is stable.
-
Changes on staging first
Every change is tested on a staging copy before it reaches your users.
-
Yours from day one
Code repo, cloud account and domain in your company's name; you can remove our access at any time.
-
Hours that overlap yours
We are on IST: 4.5 to 5.5 hours ahead of London, 9.5 to 10.5 ahead of New York.

Speed, security and care
Fast, safe and kept up to date.
A PHP application keeps ageing after it goes live: PHP versions reach the end of their security fixes, packages move on, and more users and data arrive. We look after the code and the server it runs on.
-
Fast pages and queries
Slow database queries found and tuned, results cached and API responses trimmed, so pages answer quickly.
-
Updates without surprises
PHP and Composer package updates made on staging first, with the tests run before they go live.
-
Backups and alerts
Database backups, error logging and alerts when something on the server stops.
-
Security basics, done
Validated input, prepared database queries, secrets kept out of the code and a PHP version that still gets security fixes.
Cost
What does a PHP project cost?
Every application is different, so we quote after a short call, not from a price list. Within two working days you get an approach, a rough timeline and a rough cost range. No charge, no commitment.
What changes the price
-
The state of the code
How much of an existing application is tidy, tested and documented.
-
The version gap
How far the PHP version and packages are behind a current one.
-
Features and user roles
How many screens, workflows and kinds of user the work touches.
-
Integrations
Payment gateways, CRMs, analytics and outside APIs, and how they connect.
-
Front end
Keeping the current screens, or a new front end on the backend.
-
Support after launch
Monitoring, updates, fixes and new features once it is live.
FAQ
PHP development questions
Straight answers, with the project behind each one.
How much does PHP development cost?
It depends on the state of any existing code, how far its PHP version is behind, the features and integrations, and whether a new front end is involved. We do not sell fixed packages. After a short call, we send an approach, a rough timeline and a rough cost range within two working days, with no charge and no commitment.
How long does a PHP project take?
A small fix or a single tool takes far less time than an upgrade of a large, older application. We give you a realistic timeline after the first call, and you see the work on a staging link as it is done.
What is core PHP?
Core PHP means PHP written without a framework such as Laravel or CodeIgniter. It suits small sites, forms and scripts, and many older applications are built this way. We write new core PHP when it fits, and look after existing core PHP code.
Should I use plain PHP, Laravel or another framework?
We work with all of them, so the answer depends on your project. Plain PHP suits small jobs and code you already run; Laravel suits new applications with accounts, roles and payments; an application already on CodeIgniter, Yii or CakePHP often needs care and upgrades more than a rewrite. We tell you which fits after the first call.
Can you upgrade our application to a newer PHP version?
Yes. We read the code, set up a staging copy, clean up the parts that would break and add tests, then move the PHP version and packages up step by step. For LFT, a legal application on a legacy PHP and Yii stack, the architecture clean-up comes first and the move to PHP 8 is planned for once it is stable.
Can you take over a PHP application another team built?
Yes. We start with a code audit: the PHP version, the framework, the packages, the hosting and the risky parts. Then we keep it running with updates and fixes while we tidy it, as we do for the LFT application.
Do we have to rewrite our PHP backend to get a faster site?
Not always. MotionLasers kept its Core PHP backend: we restructured key parts, reworked the API responses to come back faster and put a new Next.js storefront in front of it. Its product listing pages went from PageSpeed 30 to 90+.
Do you work with CodeIgniter, Yii and CakePHP?
Yes, as well as Laravel. LFT runs on Yii. Each framework has its own page: CodeIgniter, Yii and CakePHP development.
Who owns the code?
You do. The code repo, cloud account and domain are in your company's name; our team joins as collaborators, and you can remove our access at any time. You see the work on a staging link as it is done.
Do you work with clients outside India?
Yes. Our team is in Jaipur on IST, 4.5 to 5.5 hours ahead of London and 9.5 to 10.5 ahead of New York, and works with clients in the US, the UK, Europe, Australia and the UAE. Our UK company, Provis Global Ltd, is registered in the United Kingdom.
