CodeIgniter 3 to 4 Upgrade Helper

Hi, everyone.

I started to develop a tool which reduces upgrade costs from CodeIgniter3 to CodeIgniter4.

https://github.com/kenjis/ci3-to-4-upgrade-helper

This project is under early development.

It provides compatible interfaces for common use cases in CodeIgniter3 apps.
You can run the following code on CodeIgniter4.

PHP Code:

<?php
namespace App\Models;

use Kenjis\CI3Compatible\Core\CI_Model;

class News_model extends CI_Model
{
    public function __construct()
    {
        parent::__construct();

        $this->load->database();
    }

    public function get_news($slug = false)
    {
        if ($slug === false) {
            $query = $this->db->get('news');
            return $query->result_array();
        }

        $query = $this->db->get_where('news', ['slug' => $slug]);
        return $query->row_array();
    }

    public function set_news()
    {
        $this->load->helper('url');

        $slug = url_title($this->input->post('title'), '-', true);

        $data = [
            'title' => $this->input->post('title'),
            'slug'  => $slug,
            'text'  => $this->input->post('text')
        ];

        return $this->db->insert('news', $data);
    }
}

I get an error that says:

"""
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires kenjis/ci3-to-4-upgrade-helper 1.x-dev -> satisfiable by kenjis/ci3-to-4-upgrade-helper[1.x-dev].
    - kenjis/ci3-to-4-upgrade-helper 1.x-dev requires php ^7.3 -> your php version (8.0.10) does not satisfy that requirement.
"""

I think it may be resolved by adding this to composer.json file in ci3-to-4-upgrade-helper repository:

"php": "^7.3|^8.0",

Can you please check this error out and let me know?

Thank you for reporting.

I added ^8.0 in 1.x branch.

Now you can install kenjis/ci3-to-4-upgrade-helper:1.x-dev on PHP 8.0.

Some functions were broken with progress of CI4 development.
I fixed them and made all tests pass.

I will check more with CI4 apps, and would release the next version.

If you get something wrong, let me know.
