helper file in php code example

Example: autoload helper in laravel

1. Create a helpers.php file in your app folder and load it up with composer:

"autoload": {
    "classmap": [
        ...
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "files": [
        "app/helpers.php" // <---- ADD THIS
    ]
},

2. After adding that to your composer.json file, run the following command:
	composer dump-autoload

3. If you dont like keeping your helpers.php file in your app directory
(because it is not a PSR-4 namespaced class file), you can do what the 
laravel.com website does: store the helpers.php in the bootstrap directory. 
Remember to set it in your composer.json file:

"autoload": {
  ..........
    
  "files": [
      "app/Helpers/helpers.php"
  ]
  
  ..............
}
