General Laravel Development Information

See PHP General for general PHP development information.

Dependency Injection

• Where possible use dependency injection to resolve classes
• When that is not possible, use the app() helper function

Example

class UserController
{
    public function __construct(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function index()
    {
        return $this->userRepository->all();
    }
}

class ConvertFeetToInches
{
    public function execute($length, $measurement = Measurement::INCHES)
    {
        if ($measurement === Measurement::METERS) {
            $length = app(ConvertMetersToFeet::class)->execute($length);
        }
    
        return $feet * 12;
    }
}

Facades and Helpers

• Where possible use helper functions
• When that is not possible, use Facades
• Use the shorter helper functions over the chained methods

Example

session('cart');
// vs
$request->session()->get('cart');

Helpers vs PHP Functions

• Use Laravel helper functions over PHP functions

Example

// Laravel helper function
Str::position('This is my name', 'my');
// over PHP function
strpos('This is my name', 'my');
