A message to Russian 🇷🇺 people

If you currently live in Russia, please read this message.

Purpose

Message Scheduler implements persistent storage for any kind of message objects for all the idle time before it actually should be dispatched for handling. Dispatching can happen at exact trigger time or using recurrence rule which determines a set of times when the execution mechanism trigger the message.

Install

composer require brzuchal/scheduler

Usage

use Brzuchal\Scheduler\Executor\SimpleScheduleExecutor;
use Brzuchal\Scheduler\MessageScheduler;
use Brzuchal\Scheduler\Store\PdoScheduleStore;

$store = new PdoScheduleStore(new PDO('sqlite:scheduler.sqlite'));
$scheduler = new MessageScheduler($store);
$executor = new SimpleScheduleExecutor($store, var_dump(...));

// Scheduling message
$scheduler->schedule(new DateTimeImmutable('tomorrow 09:00:00'), new \FooMessage());

// Execute all pending messages
$dateTime = new DateTimeImmutable('now');
foreach ($store->findPendingSchedules($dateTime) as $identifier) {
    $executor->execute($identifier);
}

Note! PDO store requires manual setup depending on database platform used. See schema.sql for example schema.
