Use Laravel seed and sql files to populate database

Run php artisan db:seed at the command line.

class DatabaseSeeder extends Seeder {

    public function run()
    {
        Eloquent::unguard();

        $this->call('UserTableSeeder');
        $this->command->info('User table seeded!');

        $path="app/developer_docs/countries.sql";
        DB::unprepared(file_get_contents($path));
        $this->command->info('Country table seeded!');
    }
}
