Installation process using XAMPP
There are several processes of installation. Here I am going to use XAMPP as an open-source cross-platform web server that contains MariaDB, PHP, and Perl. If your system doesn’t have you may download from here based on your operating system and install it. Now, download CodeIgniter-4 from the official website.

After downloading the CodeIgniter-4, Go to the htdocs folder. Let, you are installed xampp on Local disk D so you should be able to find htdocs folder on your ‘Local disk D’ under xampp folder (D:\xampp\htdocs). Now create a folder under htdocs and give it a name such as ‘codeigniter’ then paste all the extracted files from “framework-4.0.3.zip” which downloaded before.

Open XAMPP and click the start button to activate Apache and MySQL.

Now open your browser and type: http://localhost/codeigniter/public.

Congrats! Finally, you have done it! Thank You.
