How to add this as a global helper function in laravel?

1 - Create a `Helpers` directory for your helper functions in the app directory 
    `mkdir app/Helpers' .

2 - Download the `Indian_currency_format.php` file and save it to Helpers directory.

3 - In your composer.json add the file to "files" attribute of autoload so that it can be loaded by composer using PSR-4 autoloading 
    (see https://getcomposer.org/doc/04-schema.md#psr-4), 

    like so:
            "autoload": {
                "classmap": [
                    "database/seeds",
                    "database/factories"
                 ],
                 "psr-4": {
                    "App\\": "app/"
                 },
                 "files": [
                    "app/Helpers/IND_money_format.php"
                 ]
            },

 4 - Finally run `composer dump-autoload` to refresh autoload cache.
