laravel updateOrCreate

// If there's a flight from Oakland to San Diego, set the price to $99.
// If no matching model exists, create one.
$flight = App\Flight::updateOrCreate(
    ['departure' => 'Oakland', 'destination' => 'San Diego'],
    ['price' => 99, 'discounted' => 1]
);

laravel find by

// Retrieve a model by its primary key...
$flight = App\Flight::find(1);

// Retrieve the first model matching the query constraints...
$flight = App\Flight::where('active', 1)->first();

// Shorthand for retrieving the first model matching the query constraints...
$flight = App\Flight::firstWhere('active', 1);

laravel where in

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get()

                ->whereMonth('created_at', '12')

eloquent firstOrCreate

firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.
