use Illuminate\Support\Facades\Schema;
 
 return new class extends Migration {
 
  /**
  * Run the migrations.
  *
 * @return void
 */
 public function up()
   {
    Schema::table('users', function (Blueprint $table) {
     $table->string('name')->nullable();
    });
   }
};

    Laravel 9 adds two new, convenient helper functions that you may use in your own application.

str : 

    The str function returns a new Illuminate\Support\Stringable instance for the given string. 

$string = str('Websolutionstuff')->append('| Web Developing Website');
 
// 'Websolutiionstuff | Web Developing Website'

    to_route :

    The to_route function generates a redirect HTTP response for a given named route.

return to_route('users.show', ['user' => 1]);

    In laravel 9 you can write queries like the below code.

return Model::query()
	->whereNotExists(function($query) {
		// $query is a Query\Builder
	})
	->whereHas('relation', function($query) {
		// $query is an Eloquent\Builder
	})
	->with('relation', function($query) {
		// $query is an Eloquent\Relation
	});

    In laravel 9 add PHP 8 string functions. It's \Illuminate\Support\Str class.

• str_contains()
• str_starts_with()
• str_ends_with()

    You may now use the controller method to define the common controller for all of the routes within the group

use App\Http\Controllers\OrderController;
 
Route::controller(OrderController::class)->group(function () {
    Route::get('/orders/{id}', 'show');
    Route::post('/orders', 'store');
});
