🗄️ Eloquent ORM & Models

Eloquent is the heart of Laravel's database interaction. Expect questions on relationships, scopes, and performance.

Q1 How do you define a one-to-many relationship in Eloquent?

📌 Example

// User model (one)
        public function posts()
        {
            return $this->hasMany(Post::class);
        }

        // Post model (many)
        public function user()
        {
            return $this->belongsTo(User::class);
        }

Q2 What is the N+1 query problem and how do you solve it?

The N+1 problem occurs when you retrieve data and then loop through it, making additional queries for each item. Solve it with eager loading using with().

📌 Example

// ❌ N+1 problem
        $users = User::all();
        foreach ($users as $user) {
            echo $user->posts->count();  // executes N additional queries
        }

        // ✅ Eager loaded (only 2 queries)
        $users = User::with('posts')->get();
        foreach ($users as $user) {
            echo $user->posts->count();
        }

Q3 What are Eloquent scopes and how do you use them?

Scopes allow you to encapsulate common query constraints. Define them in your model and reuse them.

📌 Example

// In User model
        public function scopeActive($query)
        {
            return $query->where('active', 1);
        }

        public function scopeRecent($query)
        {
            return $query->orderBy('created_at', 'desc');
        }

        // Usage
        $users = User::active()->recent()->get();

Q4 How do you handle soft deletes in Laravel?

Soft deletes allow you to "delete" records without removing them from the database. Use the SoftDeletes trait.

📌 Example

use Illuminate\Database\Eloquent\SoftDeletes;

        class Post extends Model
        {
            use SoftDeletes;

            protected $dates = ['deleted_at'];
        }

        // Soft delete
        $post->delete();

        // Restore
        $post->restore();

        // Get only trashed
        $posts = Post::onlyTrashed()->get();

        // With trashed
        $posts = Post::withTrashed()->get();

Q5 What is the difference between update() and save() on an Eloquent model?

save() is a method on the model instance that persists changes to the database. update() is a mass-assignment method that updates multiple attributes at once.

📌 Example

// save() - instance method
        $user = User::find(1);
        $user->name = 'John';
        $user->save();

        // update() - mass assignment
        User::where('active', 1)->update(['status' => 'active']);

🛤️ Routing & Controllers

Routing is how Laravel maps HTTP requests to code. Here are key interview questions.

Q6 What is the difference between Route::get() and Route::match()?

Route::get() responds only to GET requests. Route::match() accepts an array of HTTP verbs.

📌 Example

Route::get('/profile', [ProfileController::class, 'show']);

        Route::match(['get', 'post'], '/dashboard', [DashboardController::class, 'index']);

Q7 How do you pass parameters to routes?

Use curly braces in the URI and type-hint parameters in the controller method.

📌 Example

Route::get('/user/{id}', function ($id) {
            return User::find($id);
        });

        Route::get('/post/{slug}', [PostController::class, 'show']);

        // With optional parameter
        Route::get('/user/{name?}', function ($name = null) {
            return $name ?? 'Guest';
        });

Q8 What is route model binding and how does it work?

Route model binding automatically injects the model instance based on the route parameter. Use Route::bind() or implicit binding.

📌 Example

// Implicit binding (Laravel resolves by ID)
        Route::get('/post/{post}', [PostController::class, 'show']);

        // In controller
        public function show(Post $post)
        {
            return view('post.show', compact('post'));
        }

        // Custom binding
        Route::bind('post', function ($value) {
            return Post::where('slug', $value)->firstOrFail();
        });

Q9 What are route groups and why use them?

Route groups allow you to share attributes (middleware, prefix, namespace) across multiple routes.

📌 Example

Route::middleware(['auth', 'verified'])->group(function () {
            Route::get('/dashboard', [DashboardController::class, 'index']);
            Route::get('/settings', [SettingsController::class, 'index']);
        });

        Route::prefix('admin')->namespace('Admin')->group(function () {
            Route::get('/users', [UserController::class, 'index']);
        });

🎨 Blade Templates

Blade is Laravel's powerful templating engine. Expect practical questions on directives and layouts.

Q10 What is the difference between @php and @raw?

@php executes PHP code inside Blade. @raw outputs raw HTML without escaping.

📌 Example

@php
            $var = 'Hello';
        @endphp

        @raw(<div>Unescaped HTML</div>)

Q11 How do you use layouts and sections in Blade?

Use @extends, @section, and @yield to create reusable layouts.

📌 Example — layout.blade.php

<html>
            <body>
                @yield('content')
                @yield('scripts')
            </body>
        </html>

📌 Example — child.blade.php

@extends('layout')

        @section('content')
            <h1>Home Page</h1>
        @endsection

        @section('scripts')
            <script>console.log('Loaded!');</script>
        @endsection

Q12 What are Blade components and how are they different from sections?

Blade components are self-contained, reusable UI elements with their own logic and views. Sections are for content injection into layouts.

📌 Example — component

// App\View\Components\Alert.php
        class Alert extends Component
        {
            public $type;
            public $message;

            public function render()
            {
                return view('components.alert');
            }
        }

        // In Blade
        <x-alert type="success" message="Saved!" />

Q13 How do you escape HTML in Blade?

Use {{ $variable }} for auto‑escaping, and {!! $variable !!} to output raw HTML without escaping.

📌 Example

{{ $user->name }}   // Escaped
        {!! $user->bio !!}   // Raw HTML (use with caution)

🛡️ Middleware & Security

Q14 What is middleware and how do you create one?

Middleware acts as a filter for HTTP requests. Create one using php artisan make:middleware.

📌 Example

php artisan make:middleware CheckAge

        // In CheckAge middleware
        public function handle($request, Closure $next)
        {
            if ($request->age < 18) {
                return redirect('home');
            }
            return $next($request);
        }

        // Register in kernel
        protected $routeMiddleware = [
            'check.age' => \App\Http\Middleware\CheckAge::class,
        ];

        // Apply to route
        Route::get('/adult', [AdultController::class, 'index'])->middleware('check.age');

Q15 What is CSRF protection and how does Laravel handle it?

Laravel generates a CSRF token for every session and verifies it on POST/PUT/DELETE requests. Use @csrf in forms.

📌 Example

<form method="POST" action="/profile">
            @csrf
            <input type="text" name="name" />
            <button type="submit">Update</button>
        </form>

Q16 How do you secure API routes in Laravel?

Use Laravel Sanctum or Passport for API authentication, and apply auth:sanctum middleware.

📌 Example

Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
            return $request->user();
        });

📦 Queues & Jobs

Q17 What are queues and when should you use them?

Queues defer time‑consuming tasks (email, image processing, API calls) to improve response times.

📌 Example

// Create a job
        php artisan make:job SendWelcomeEmail

        // In your controller
        SendWelcomeEmail::dispatch($user);

        // Job class
        class SendWelcomeEmail implements ShouldQueue
        {
            use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

            protected $user;

            public function __construct($user)
            {
                $this->user = $user;
            }

            public function handle()
            {
                Mail::to($this->user->email)->send(new WelcomeMail());
            }
        }

Q18 What is the difference between dispatch() and dispatchNow()?

dispatch() pushes the job to the queue; dispatchNow() runs it synchronously in the current request.

Q19 How do you handle failed jobs?

Use failed_jobs table, define failed() method, and use queue:retry command.

📌 Example

// In job class
        public function failed($exception)
        {
            Log::error('Job failed: ' . $exception->getMessage());
        }

        // Retry failed jobs
        php artisan queue:retry all

🔔 Events & Listeners

Q20 What are events and listeners in Laravel?

Events are signals that something happened; listeners are classes that respond to those events.

📌 Example

// Create event
        php artisan make:event UserRegistered

        // Create listener
        php artisan make:listener SendWelcomeEmail --event=UserRegistered

        // Event class
        class UserRegistered
        {
            public $user;
            public function __construct($user) { $this->user = $user; }
        }

        // Listener class
        class SendWelcomeEmail
        {
            public function handle(UserRegistered $event)
            {
                Mail::to($event->user->email)->send(...);
            }
        }

        // Fire event
        event(new UserRegistered($user));

🧪 Testing & Debugging

Q21 How do you write a test for a controller in Laravel?

Use PHPUnit and Laravel's testing helpers.

📌 Example

public function test_user_can_view_dashboard()
        {
            $user = User::factory()->create();
            $this->actingAs($user)
                ->get('/dashboard')
                ->assertStatus(200)
                ->assertSee('Welcome');
        }

Q22 What is the difference between assertDatabaseHas() and assertDatabaseMissing()?

They check for the existence or absence of a record in the database matching a given array of criteria.

📌 Example

$this->assertDatabaseHas('users', ['email' => 'john@example.com']);
        $this->assertDatabaseMissing('users', ['email' => 'old@example.com']);

⚙️ Service Providers & Facades

Q23 What is a service provider and when would you create one?

Service providers are the central place to register bindings, services, and events. Create one for custom services.

📌 Example

php artisan make:provider AnalyticsServiceProvider

        // In register()
        public function register()
        {
            $this->app->bind('analytics', function ($app) {
                return new AnalyticsService();
            });
        }

        // In boot()
        public function boot()
        {
            View::composer('*', function ($view) {
                $view->with('analytics', app('analytics'));
            });
        }

Q24 What are facades and when should you use them?

Facades provide a static interface to services in the container. Use them for readability and convenience.

📌 Example

use Illuminate\Support\Facades\Cache;
        use Illuminate\Support\Facades\Log;

        Cache::put('key', 'value', 60);
        Log::info('User logged in');

📡 API Development

Q25 How do you create a RESTful API in Laravel?

Use controllers that return JSON responses, and use API resources to transform data.

📌 Example

// In controller
        public function index()
        {
            return UserResource::collection(User::paginate());
        }

        public function show($id)
        {
            return new UserResource(User::findOrFail($id));
        }

        // API routes
        Route::apiResource('/users', UserController::class);

Q26 What is API rate limiting and how do you implement it?

Use Laravel's built-in rate limiter. Define in app/Http/Kernel.php or using RateLimiter::for().

📌 Example

// In App\Http\Kernel
        protected $middlewareGroups = [
            'api' => [
                \Illuminate\Routing\Middleware\ThrottleRequests::class . ':60,1',
            ],
        ];

        // Or using named rate limiter
        RateLimiter::for('api', function ($job) {
            return Limit::perMinute(100);
        });
