Post Booster

booster.php

<?php

// The script will keep its place based on a file called min_id, which should contain
// the ID of the post after which we should start boosting. If we don't specify an ID,
// we'll grab the latest 40 posts and boost them, writing the min_id file as we go
// through the list. So if you don't want to potentially duplicate boosts, make sure
// a status ID is in that file.

// To run this script, you'll need to install PHP. You can do that on an Ubuntu 22.04 box by running
// sudo apt install php-cli

// To run this script on a schedule, e.g. every minute, add a command to your crontab, via
// EDITOR=nano crontab -e
// and then add e.g.
// * * * * * php booster.php phpc.social php AUTH_TOKEN_HERE >> booster.log

// To get an auth token, go to /settings/applications, then click New Application,
// then fill out an application name, then select the write:statuses scope, then click
// Submit. Click the application once created, then grab the "Your access token" field.
