Sometimes we need to create a helper function on the Laravel project to use a function on the whole project.

To create a helper function, we need to create a helper file in the following folder -

app\helpers\helpers.php

on that folder write your function like this -

<?phpif (!function_exists('abc')) {    function abc($parameter)    {        // statement         return xyz;    }}

after that we need to add this folder in autoloader on -

composer.json

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

Once you add a new path to the files array, you need to dump the autoloader-

composer dump-autoload

Then you can access this "abc()" function from anywhere in this project.
