Helper classess in laravel

      In most case, we want to extend our Laravel applications capabilities by adding helper class.
It is not a best practice to insert this classess inside Controller and Model.

so we have to write our classess in separate files and group it by folder

Here let us have a look how we add helper classess in laravel

1.    We have app folder on root folder of laravel.There we can create a Libraries folder inside app folder.

2.  We can create a class/helper file and we can write a our custom class there, on the top of custom class we have to define namespace our_folder_name;

namespace our_folder_name

for example ,

 
//here my folder name is Libraries
namespace Libraries;

class className{
    
    //class methodes
    
}

Now we can go to our controller and on top we can include our helper class

use Libraries\filename as filename;

And we can go to compser, inside autoloder we can add “app/foldername”

app/foldername

"autoload": {
		"classmap": [
			"app/commands",
			"app/controllers",
			"app/models",
			"app/database/migrations",
			"app/database/seeds",
			"app/tests/TestCase.php",
 			"app/Libraries",// we've added classes folder on compose
		]
	},

And we can update composer by using below comment

 composer dump

Now we can use our helper class in our controller

  $test = new className();

All my samples files are given below
Library/className.php

<?php
 namespace Libraries;

class className{
    
    //class methodes
    
    function testmesthode(){
        
        return "Hello world";
    }
    
}

testController.php

<?php

use Libraries\className as className;

class testController extends BaseController {
    
    
    function index(){
        
        $test = new className();
        echo $test->testmesthode();

    }
    
}

compser file

"autoload": {
		"classmap": [
			"app/commands",
			"app/controllers",
			"app/models",
			"app/database/migrations",
			"app/database/seeds",
			"app/tests/TestCase.php",
 			"app/Libraries",// we've added classes folder on Laravel ClassLoader
		]
	},
