laravel query with table where condition code example

Example 1: laravel chunk select

DB::table('users')->chunk(100, function($users)
{
    foreach ($users as $user)
    {
        //
    }
});

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);
