PHP API developmentfor Next.js and mobile apps
For teams whose data lives in a PHP app or MySQL database and now needs to reach a Next.js site or a mobile app. I’ve built PHP backends since 2013 and wrote up how I do it for Next.js products.
This site works the same way: WordPress, written in PHP, serves posts over its REST API, and Next.js renders them.
What PHP API development means for a Next.js product
PHP API development means exposing your data and business rules through HTTP endpoints that other apps call. For a Next.js product, that usually means a REST API in Laravel or plain PHP that returns JSON, checks who is asking, and validates every input. Your PHP backend keeps doing what it does well, and the front end can change without touching it.
I walk through the whole approach in PHP API development for Next.js.
When a PHP REST API is the right call
If you have no PHP backend yet, a Next.js route handler may be enough. I explain that option in building APIs with the Next.js App Router.
Good fit
- Your data and business rules already live in a PHP app or MySQL database
- A new Next.js front end or mobile app needs that data
- Partners or internal tools need controlled access to the same records
- The current API has no docs and nobody is sure what it returns
Probably skip the PHP API
- There is no PHP code yet and your team writes TypeScript
- You only need a contact form or a handful of static pages
What you get
Endpoints shaped around your screens
Each endpoint returns what a page needs, so the front end makes fewer calls and loads faster.
Auth and validation on every route
Token or session auth, role checks, and input validation, so callers can only do what they are allowed to.
Caching where the load is
Cache headers and Redis for heavy reads, so a traffic spike hits the cache before it hits MySQL.
Docs your front-end developer can read
An OpenAPI spec with example requests, so nobody guesses field names or error formats.
If the slow part is the database itself, see MySQL database optimization.
Laravel API and the rest of the stack
How an API project runs
Map the screens
List what each page or app screen needs from your data.
Agree the contract
Endpoints and fields written as an OpenAPI spec you approve first.
Build and test
Laravel or your existing PHP, with tests against the spec.
Connect and ship
Wire it to your Next.js app, deploy, and hand over the docs.
PHP API development FAQ
How much does PHP API development cost?+
It depends on how many endpoints you need and how tangled the existing code is, so I scope each project separately. Tell me what the front end needs and where the data lives. You get an endpoint plan and a quote before any work starts.
Can you build the API on my existing PHP app, or does it need a rewrite?+
Usually on top of what you have. I add an API layer next to your current code and reuse its models and rules. A rewrite only makes sense when the existing code cannot be tested or changed safely, and I will tell you if that is the case after reading it.
Will the current app go down while you add the API?+
The API ships as new routes next to the running app, so current users keep working. I test it on a staging copy first and switch the front end over once it passes.
Should the API be in Laravel or plain PHP?+
For a new API I use Laravel, because routing, validation, and auth come built in. If your app is plain PHP or CodeIgniter, I can add a small API layer in the same style so your team does not have to learn a new framework.
Who maintains the API after launch?+
You own the code. The OpenAPI spec and a short README explain every endpoint, so your team or another developer can extend it. I can stay on for changes if you want.
Need your PHP data in a Next.js app?
Tell me what the front end needs and where the data lives. I’ll send back an endpoint plan and a quote before you commit to anything.
