Documentation, API URL

[xdpirate]

Hi, I attempted to run this, but to no avail.

Upon cloning the repo and opening index.php, one is presented with a blank page.

Adding

error_reporting(E_ALL);
ini_set("display_errors", 1);

reveals the issue:

Fatal error: Uncaught ValueError: Path cannot be empty in /var/www/html/RPCN-Player-Count-Viewer/index.php:28 Stack trace: #0 /var/www/html/RPCN-Player-Count-Viewer/index.php(28): file_get_contents() #1 {main} thrown in /var/www/html/RPCN-Player-Count-Viewer/index.php on line 28

Having to supply a URL to an API isn't documented in the readme.

Additionally, this API URL seems to be nowhere to be found. A web search for "rpcn api" or "rpcn api url" yields no relevant results.

Using np.rpcs3.net, as mentioned here, yields a permission error:

Warning: file_put_contents(/var/www/html/RPCN-Player-Count-Viewer/log.txt): Failed to open stream: Permission denied in /var/www/html/RPCN-Player-Count-Viewer/index.php on line 12
Error: Unable to connect to API. Check log for details.

What's going on here? What URL is expected in the $api_url variable? Why isn't it prefilled?

My environment:

$ php --version
PHP 8.3.14 (cli) (built: Nov 25 2024 18:07:16) (NTS)

$ apache2 -v
Server version: Apache/2.4.52 (Ubuntu)

After going through rpcn's code and pinging the crap out of the server the url is
http://np.rpcs3.net:31333/rpcn_stats
