laravel save into database using model code example

Example 1: where () laravel Eloquent

//los signos de igualdad pueden ser: ">=", "<=", "=", ">", "<"
$user = User::where("estado","=",1)->find(10);

Example 2: laravel find query

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

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

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