Have you had experience writing PHP code on frameworks or pure PHP?

Yes, I have experience writing PHP code both in pure PHP and using frameworks.

In pure PHP, I wrote scripts for form processing, interacting with databases via PDO, and implementing simple business logic.

With frameworks, I have worked with Laravel and Symfony, where I used MVC architecture, created routes, controllers, models, and worked with migrations and ORM.

An example of a simple controller in Laravel:

<?php

namespace App\Http\Controllers;

use App\Models\Order;
use Illuminate\Http\Request;

class OrderController extends Controller
{
    public function index()
    {
        $orders = Order::all();
        return view('orders.index', compact('orders'));
    }

    public function store(Request $request)
    {
        $validated = $request->validate([
            'product_id' => 'required|integer',
            'quantity' => 'required|integer|min:1',
        ]);

        Order::create($validated);

        return redirect()->route('orders.index');
    }
}

This experience allows me to develop and maintain backend logic effectively.
