Laravel - custom classes don't work

Question

I was reading some tutorials on creating custom classes for Laravel. I followed instructions and did exactly what tutorials say:

1. Created new folder laravel/app/libraries/graphics/

2. Edited laravel/app/start/global.php where I added:

   app_path().'/libraries/graphics',
   

3. Created new file in laravel/app/libraries/graphics/ named Image.php with this code:

   <?php  namespace graphics/Image;
   
   class Image {
   
       public static function hello() {
   
       return 'Hello';
   
       }
   }
   

4. Used composer dump-autload command

5. Route::get('/' , function() { return Graphics\Image::hello(); } ); is returning error:

Use of undefined constant graphics - assumed 'graphics'

I also added "app/libraries/graphics/Image.php"line into composer.json autload section, which should not be neccessary. Why I am getting this error? Every tutorial shows the same procedure for this, but why it doesn't work?

Answer 1

Shouldn't your namespace just be graphics? The current file creates graphics\Image\Image. Try removing Image from your namespace.

<?php  namespace graphics;

class Image {

    public static function hello() {

    return 'Hello';

    }
}

Answer 2

Have you tried using artisan dump-autoload instead?

It will clear all of Laravel's compiled code.

See here: What are differences between "php artisan dump-autoload" and "composer dump-autoload"

Answer 3

You don't need to confusion for yourself. I'm resolve issue into Laravel 5. You don't need to add "app/libraries/graphics/Image.php"line into composer.json autload section because By default, app directory is namespaced under App and is autoloaded by Composer using the PSR-4 autoloading standard.

<?php 
namespace App\libraries\graphics;
class Image {
     public static function hello() {
         return 'Hello';
     }
}

and now use your Image Class from your route.

Route::get('graphics',function(){
    echo \App\libraries\graphics\Image::hello();
});
