How to implement automatic task processing after queue completion in Laravel?

In Laravel, to automatically handle tasks after queues are completed, you can use the JobProcessed event or callback methods within the tasks themselves.

1. Using the JobProcessed event:

You can subscribe to the event in a service provider:

use Illuminate\Queue\Events\JobProcessed;
use Illuminate\Support\Facades\Event;

public function boot()
{
    Event::listen(JobProcessed::class, function ($event) {
        // Logic after task processing
        // $event->job contains information about the task
    });
}

2. The handle and __destruct methods in the task class:

You can define a handle() method in the task class for the main logic, and in the __destruct() method, include code that runs after the task completes.

3. Using the then() method for task chaining:

Laravel allows queuing tasks that will be executed after the successful completion of previous tasks.

dispatch(new FirstJob())->then(function () {
    dispatch(new SecondJob());
});

Thus, automation of post-queue processing is achieved through events or task chains.
