Instructions

Create a file called helpers.php in the app/ directory. Paste the code inside it.

Go to composer.json and add files to autoload so that it looks like this:

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

Run composer dump-autoload to load the newly created helpers file.

public static function config()
{
if (!function_exists('config_path')) {
function config_path($path = '')
{
return app()->basePath() . '/config' . ($path ? '/' . $path : $path);
}
}
}
