REST APIs are the backbone of modern web applications. PHP provides flexibility to build APIs following best practices.

Routing and Controllers

Use proper routing and controllers to separate endpoints:

Route::get('/posts', [PostController::class, 'index']);
Route::post('/posts', [PostController::class, 'store']);

JSON Responses

Always respond with consistent JSON structure:

{
    "status": "success",
    "data": { ... }
}

Authentication & Security

  • JWT or OAuth for auth
  • Validation on input
  • Rate limiting for public endpoints

Pagination & Filtering

Use query parameters to allow flexible filtering:

GET /posts?page=2&limit=20&category=3

Conclusion

Following these best practices in PHP ensures your APIs are maintainable, secure, and scalable.
