Create custom class or library class in Laravel 8 / 9

Laravel provides various packages and library to enhance our application features and functionalities but sometime we want our own class to handle the few features of the application. Thus I this article i will show you to create a class and use it using the alias or directly from the namespace name.

Let’s begin the tutorial of custom helper functions step by step

Step 1 : Create a class file

First step is create a helper file in app folder or we can create a folder named as Lib in app folder then we can create multiple files in that folder. in this example i am going to create a file in app/Lib/PaymentHelper.php

<?php 
namespace \App\Lib;

class PaymentHelper{

public $key='test_key';

  function getConfig(){
    return $this->key;
  }

}

Step 2 : Create Routes

Now, Create a route to check our implementation on controller or route itself using anonymous function.

<?php

use Illuminate\Support\Facades\Route;
 
Route::get('/helper',function(){
   
   $Payment=new \App\Lib\PaymentHelper();
    return $Payment->getConfig();
}); 

Or in controller

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ArticleController;

 
Route::get('/helper',[ArticleController::class, 'test']); 

Create a controller in app\Http\Controllers\ArticleController and method helper

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
user App\Lib\PaymentHelper;

class ArticleController extends Controller
{
    public function test(Request $request)
    {
        $Payment=new PaymentHelper();
        return $Payment->getConfig();
    }
}
?>

In the same way we can use it in our view file.
