Using the Laravel context() Helper for Managing Application Context Data

Easily manage context data in a Laravel application? The new context() helper function offers an elegant solution for handling context information throughout the application lifecycle.

Basic Usage

The context() helper provides several basic usages:

// 将数据添加到上下文
context(['user' => auth()->user()]);

// 获取整个上下文对象
$context = context();

// 获取特定值
$user = context('user');

// 使用默认后备获取
$theme = context('theme', 'light');

Real Example

Below is an example of using the context() function in a multi‑tenant application:

class TenantMiddleware
{
    public function handle($request, $next)
    {
        $tenant = Tenant::fromDomain($request->getHost());

        context([
            'tenant' => $tenant,
            'tenant_settings' => $tenant->settings,
            'tenant_features' => $tenant->activeFeatures
        ]);

        return $next($request);
    }
}

class OrderController extends Controller
{
    public function store(OrderRequest $request)
    {
        $tenant = context('tenant');
        $features = context('tenant_features', []);

        if (in_array('advanced_ordering', $features)) {
            return $this->handleAdvancedOrder($request);
        }

        // 常规订单处理
        $order = Order::create([
            'tenant_id' => $tenant->id,
            'user_id' => auth()->id(),
            'items' => $request->items
        ]);

        return response()->json([
            'order' => $order,
            'settings' => context('tenant_settings')
        ]);
    }
}

The context() helper function makes it convenient to maintain and access shared data during the request lifecycle.
