CodeIgniter 4 Running Problem

Hi. 

I am new to CodeIgniter 4. I am facing a few problems. Please help to resolve these. 

Environment:
WAMP Server 
PHP 8.1

Installation: 
I am trying to install using Composer. But unable to get version 4.3 but get 4.19. 
Is there any possibility of using install 4.3? 

Problem:
I am following the example documentation of static pages, but receive the below error. 

class_exists() expects parameter 1 to be string, array given


Here is the code. 

Routes.php

$routes->get('/', 'Home::index');

use App\Controllers\Pages;
$routes->get("/home", [ Pages::class, "index" ]);

Pages.php

<?php

namespace App\Controllers;

use CodeIgniter\Exceptions\PageNotFoundException;


class Pages extends BaseController
{
  public function index()
  {
    return view("pages/home");
  }
}

home.php

<h1>Welcome</h1>

Looking forward to resolving the issue.

Awaiting a reply ASAP.


Thanks.

Run

Code:

composer require codeigniter4/framework:4.3.8

difficult to see what your doing and not doing .
So just to clarify routes are in app/Config/Routes.php


when you get /install codeigniter in routes you see :

Code:

$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Home');
$routes->setDefaultMethod('index');

so some default stuff set up

for my home page I have in routes :

Code:

$routes->get('/home','Home::landingpage');

so in the above a URL of the domain/home will evoke  Home ::landingpage
i.e function landingpage()   in Home controller

Then to get rid of the welcome to CI4 i made a Home.php controller containing

Code:

<?php

namespace App\Controllers;

class Home extends BaseController
{
            

           public function landingpage()
          
           {
            $data= [
            'title'=>" landing page",
            ];
             return   view('landingPage.php',$data);
           }

             public function index()
          
           {
            $data= [
            'title'=>" landing page",
            ];
             return   view('landingPage.php',$data);
           }


}

you can edit Routes to use another function of your own controller eg

Code:

$routes->get('/', 'Home::index');
// you could have a function in your pages as long as   route ties up with class::class method to be used

then for instance :

Code:

public function index()
          
           {
            $data= [
            'title'=>" landing page",
            ];
             return   view('landingPage.php',$data);
           }

So now domain.com/ or domain.com/home willn ow go to the same landing page

But i guess an edit of default routes might be needed


explantion a bit mangled as i'm in a rush to g oto Aikido , so any questions just come back

CMS CI4     I use Arch Linux by the way

Use PHP 7.4 or later.
It is better to use PHP 8.1 or later.

The end of life date for PHP 7.4 was November 28, 2022. If you are still using PHP 7.4, you should upgrade immediately.
The end of life date for PHP 8.0 will be November 26, 2023.
