Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Demo – Create Controllers

Open project into terminal and run these commands.

$ php artisan make:controller FirstController

$ php artisan make:controller SecondController

These commands will create two different controllers in application. Controllers will be created inside /app/Http/Controllers folder. Files are: FirstController.php and SecondController.php

Open SecondController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SecondController extends Controller
{
    public function exampleFirstFunction()
    {
        return "<h3>'First Function' of Second Controller</h3>";
    }

    static function exampleStaticFunction()
    {
        return "'Static Function' of Second Controller";
    }
}

Inside above controller, you can see we have two methods – exampleFirstFunction() or exampleStaticFunction().

Let’s call these methods into FirstController class.

Method #1: Call Method To Controller

Open FirstController.php and write this code into it.

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Http\Controllers\SecondController;
  
class FirstController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $result = (new SecondController)->exampleFirstFunction();
  
        dd($result);
    }
}

Concept

Load Controller

use App\Http\Controllers\SecondController;

Then,

$result = (new SecondController)->exampleFirstFunction();

Method #2: Call Method To Controller

Open FirstController.php and write this code into it.

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class FirstController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $result = app('App\Http\Controllers\SecondController')->exampleFirstFunction();
  
        dd($result);
    }
}

Concept

$result = app('App\Http\Controllers\SecondController')->exampleFirstFunction();

Method #3: Call Static Method To Controller

Open FirstController.php and write this code into it.

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class FirstController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $result = SecondController::exampleStaticFunction();
  
        dd($result);
    }
}

Concept

$result = SecondController::exampleStaticFunction();

Use :: (scope resolution operator) to call static methods.
