Laravel eloquent inserts && Update

 https://laravel.com/docs/5.7/queries#inserts

The query builder also provides an insert method for inserting records into the database table. The insert method accepts an array of column names and values:

DB::table('users')->insert(
    ['email' => 'john@example.com', 'votes' => 0]
);

You may even insert several records into the table with a single call to insert by passing an array of arrays. Each array represents a row to be inserted into the table:

DB::table('users')->insert([
    ['email' => 'taylor@example.com', 'votes' => 0],
    ['email' => 'dayle@example.com', 'votes' => 0]
]);

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);
User::insert($data);

Mass Updates
Updates can also be performed against any number of models that match a given query. In this example, all flights that are active and have a destination of San Diego will be marked as delayed:
App\Flight::where('active', 1)
          ->where('destination', 'San Diego')
          ->update(['delayed' => 1]);
