core-php	Use when creating PHP modules, services, or actions in core-* packages.

PHP Framework Patterns

Host UK PHP modules follow strict conventions. Use core php commands.

Module Structure

Boot Class Pattern

<?php

declare(strict_types=1);

namespace Core\{Name};

use Core\Php\Events\WebRoutesRegistering;
use Core\Php\Events\AdminPanelBooting;

class Boot
{
    public static array $listens = [
        WebRoutesRegistering::class => 'onWebRoutes',
        AdminPanelBooting::class => ['onAdmin', 10],  // With priority
    ];

    public function onWebRoutes(WebRoutesRegistering $event): void
    {
        $event->router->middleware('web')->group(__DIR__ . '/../routes/web.php');
    }

    public function onAdmin(AdminPanelBooting $event): void
    {
        $event->panel->resources([...]);
    }
}

Action Pattern

<?php

declare(strict_types=1);

namespace Core\{Name}\Actions;

use Core\Php\Action;

class CreateThing
{
    use Action;

    public function handle(User $user, array $data): Thing
    {
        return Thing::create([
            'user_id' => $user->id,
            ...$data,
        ]);
    }
}

// Usage: CreateThing::run($user, $validated);

Multi-Tenant Models

<?php

declare(strict_types=1);

namespace Core\{Name}\Models;

use Core\Tenant\Concerns\BelongsToWorkspace;
use Illuminate\Database\Eloquent\Model;

class Thing extends Model
{
    use BelongsToWorkspace;  // Auto-scopes queries, sets workspace_id

    protected $fillable = ['name', 'workspace_id'];
}

Rules

• Always declare(strict_types=1);
• UK English: colour, organisation, centre
• Type hints on all parameters and returns
• Pest for tests, not PHPUnit
• Flux Pro for UI, not vanilla Alpine
