I want to create a link shortening service with my scalora.link domain and my Ubuntu/Apache2.4/PHP 8.1 server. Features:

UI for creating, browsing and modifying links with simple security (e.g. fixed admin password), browsing show allow some simple analytics, total hit count, hit count per day for the last 14 days.

Creation date should be stored for each link.

The link editor should allow the user to change the destination ULR. Old URL values should be saved in the data file.

The browse UI should show short URL, destination URL, use count, creation date/time and an option to show previous destination URLs if it has been changed.

Please use the Tailwind css framework and make the pages beautiful and responsive to mobile, tablet and desktop.

Shortened URL should look like: https://scalora.link/1XXXXX
Where '1' is used for all generation one link (this code) and XXXXX are random characters in the set of uppercase letters excluding 'I' and 'O' and digits 0-9. Check for and avoid duplicates.

Use the file system for all persistent storage, a directory $DATA_DIR would hold a pretty printed JSON file for each link with all data for that link. Each file should be named with the link code followed by .json

Configuration File: short-1.conf.php

Contents:
  <?php 
    define('MAIN_DIR', '/var/www/html-scalora-link/_root_');
    define('DATA_DIR', __DIR__ . '/short-1');
    define('BASE_URL', 'https://scalora.link/');
    define('CHARSET', 'ABCDEFGHJKLMNPQRSTUVWXYZ0123456789'); // Excludes I and O
    define('PASSWORD_HASH', '$2y$10$vO6EgNMgsUOFVsrajGSfWuVC4sl5Sl1AmPlCBdyFoLjD6DMUv8MyW');
    error_reporting(E_ALL);
    ini_set("display_errors", 1);
  ?>

The PHP code for the shortener should be in a file named short-1.php and the data will be in a directory in the same location called short-1.

Use "code" for the URL parameter name when doing url rewriting.

Please provide any apache 2.4 conf file changes I need to make.

Apache Config Note: SSL and virtual host Configuration is done, just need the rewriting part
