Modernizing Legacy PHP Applications for Edge Platforms

1. The Problem with Stateful Legacy PHP Monoliths

Millions of enterprise platforms built between 2010 and 2020 run on procedural PHP scripts intermingling MySQL queries with HTML markup (`echo "div class='user'"`).

These stateful architectures rely on server-side `$_SESSION` storage, preventing horizontal autoscaling behind cloud load balancers. SoftSolex refactors legacy code bases into strictly typed, stateless APIs. Explore our dedicated Custom Software & SaaS Capability to see how we modernize legacy systems.

namespace App\Http\Controllers;

use App\Data\OrderData;
use App\Services\OrderProcessor;
use Illuminate\Http\JsonResponse;

readonly class OrderController
{
    public function __construct(private OrderProcessor $processor) {}

    public function store(OrderData $data): JsonResponse
    {
        $order = $this->processor->execute($data);
        return response()->json(['status' => 'COMMITTED', 'id' => $order->id]);
    }
}
