Create a utils\ToolBar.php file under the app directory. This is our tool class, which contains the code we defined. .

<?phpnamespace App\Utils;class ToolBar{
   public function get()
   {
       return &#39;Hello my facade&#39;;
   }}

2. Create a service provider

Execute the command in the root directory of the project: php artisan make:provider ToolServiceProvider to create a service provider and add what we just The tool class written is registered in the container.

<?phpnamespace App\Providers;use Illuminate\Support\ServiceProvider;use App\Utils\ToolBar;class ToolServiceProvider extends ServiceProvider{
   /**
    * Bootstrap the application services.
    *
    * @return void
    */
   public function boot()
   {
       //
   }

   /**
    * Register the application services.
    *
    * @return void
    */
   public function register()
   {
       $this->app->bind(&#39;tool&#39;,function(){
           return new ToolBar();
       });
   }}

3. Group registration service provider

Register the service provider we just added in the providers attribute in the config\app.php file, that is, add:

App\Providers\ToolServiceProvider::class,

4. Create a facade class

Create a facade class under the app directory, App\Facades\Tool.php, the directory here is created by myself, this You can create whatever you want. As long as it is consistent when registering later, it will be fine. The code is as follows:

<?phpnamespace App\Facades;use Illuminate\Support\Facades\Facade;class Tool extends Facade{
   protected static function getFacadeAccessor()
   {
       return &#39;tool&#39;;
   }}

5. Group registration facade class

Add the following code to the aliases attribute of config\app.php:

'Tool' => App\Facades\Tool::class,

After completing the above steps, we can call to test whether the created facade and service provider are valid
Add the following code in routes\console.php:

Artisan::command('testFacade',function(){
    dd(tool::get());});

Then in the terminal of the project root directory, call The following command:

php artisan testFacade

If Hello my facade is output, it means the registration is successful. Next, we can use the custom facade anywhere in the project.
