Helper file in very useful to create custom helper functions in Laravel app. We can use these custom helper functions app-wide.

First create the file  app/helpers.php.

 

Then either load this file in any of the core Laravel file that autoloads when the application starts. Like,

require app_path() . '/helpers.php';

 

OR, change your composer.json file and dump the autoloader.

Example:

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

 

Then Run: composer dump-auto or composer dump-autoload
