# ActivityPub Server in a Single PHP File

This is a single PHP file - and an `.htaccess file` - which acts as an extremely basic ActivityPub server.

## Getting started

This is designed to be a lightweight educational tool to show you the basics of how ActivityPub works.

There are no tests, no checks, no security features, no header verifications, no containers, no gods, no masters.

Edit the `.php` file to add a username, password, and keypair.

Upload the `.php` and `.htaccess` file to the *root* directory of your domain. For example `test.example.com/`. It will not work in a subdirectory.

Optionally, upload an `icon.png` as well to make the account look nice.

## How this works

* The `.htaccess` file transforms requests from `example.com/whatever` to `example.com/index.php?path=whatever`.
* The `index.php` file performs a specific action depending on the path requested.
* Log files are saved as .txt in the root directory.
* Post files are saved as .json in the `/posts` directory.
