Spiral¶
Spiral has two main meanings in the PHP and software engineering world.
Spiral Framework is a high-performance PHP framework built on top of RoadRunner, a Go-based application server. Unlike traditional PHP frameworks that re-bootstrap the application on every request, Spiral keeps the application alive between requests in long-running workers, significantly reducing overhead. It is well-suited for microservices, APIs, and high-throughput applications.
Spiral model, or spiral development model is a software development lifecycle model that combines iterative development with systematic risk analysis. Each iteration, or spiral, passes through four phases: planning, risk analysis, engineering, and evaluation. It is particularly suited for large, complex, or high-risk projects where requirements may evolve.
Both concepts involve iterative, incremental progression: the spiral metaphor captures the idea of building upon previous cycles.
<?php
// Spiral Framework: defining a simple controller
namespace App\Controller;
use Spiral\Router\Annotation\Route;
final class HomeController
{
#[Route(route: '/', name: 'home')]
public function index(): string
{
return 'Hello from Spiral!';
}
}
?>
