Laravel is a popular framework having high demand in the field of web development, it serves both the frontend and backend. many projects are built upon this framework, for the easiness in the development of the projects we need to have some utilities or helpers function that can be accessed globally, in this session we are going to create one for our own project which makes our life easier...

Step 1 - Create a helpers.php file inside app/helpers/helpers.php

create a file called helpers.php inside the app/helpers/ directory from your root project. if the helpers directory does not exist you need to create one inside the app directory. 

<?php
function getUserFullName() {
return auth()->user()->firstName + auth()->user()->lastName; //it will return curent user full name
}
... //register other functions here


Step 2 - Register the app/helpers/helpers.php file in composer.json

you need to register the helper in composer.json to dump it automatically. just do like this

...

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

...


Step 3 - Run composer dump-autoload & access helpers globally

now the final step is to run the command in your root project composer dump-autoload

composer dump-autoload

USE:

now you can access the functions anywhere in the project eg, blade, controller, web.php, etc.

web.php

...
Route::get('helper', function(){
    $fullname= getUserFullName();
  
    dd($fullname);
});
 ...


Final

In conclusion, creating helper functions in Laravel 8 allows you to define custom functions that can be used globally throughout your application without the need for explicit imports or namespaces. By following the steps outlined above, you can create a dedicated helper file, define your helper functions, autoload the file using Composer, and start using the helper functions across your Laravel project.

Using helper functions can help simplify code, promote code reusability, and improve the overall maintainability of your application. However, it's important to be mindful of naming conventions and avoid conflicts with existing Laravel functions or composer packages.

With the ability to create helper functions in Laravel, you can streamline your development process and enhance the functionality of your application by encapsulating commonly used code snippets in reusable functions.
