# The easiest way to create a model instance is using the 
# make:model Artisan command:

php artisan make:model Flight

# If you would like to generate a database migration when you 
# generate the model, you may use the --migration or -m option:

php artisan make:model Flight --migration
php artisan make:model Flight -m

DB::table('users')->where('id', $id)->delete();

// If no matching model exists, create one.

    ['price' => 99, 'discounted' => 1]
);

// Retrieve flight by name, or create it if it doesn't exist...
$flight = App\Flight::firstOrCreate(['name' => 'Flight 10']);

// Retrieve flight by name, or create it with the name, delayed, and arrival_time attributes...

// Retrieve by name, or instantiate...
