Logger Plugin

The Logger Plugin provides configurable logging capabilities for your application. It allows you to route logs to multiple destinations, including files, stdout, syslog, and external services like Graylog.

Installation

$ composer require phpstreamserver/logger

Example of usage

server.php

use PHPStreamServer\Core\Server;
use PHPStreamServer\Core\Worker\WorkerProcess;
use PHPStreamServer\Plugin\Logger\Handler\ConsoleHandler;
use PHPStreamServer\Plugin\Logger\LoggerPlugin;

$server = new Server();

$server->addPlugin(
    new LoggerPlugin(
        new ConsoleHandler(),
    ),
);

$server->addWorker(
    new WorkerProcess(
        name: 'Worker process',
        onStart: function (WorkerProcess $worker): void {
            $worker->logger->info('Hello from worker', ['pid' => \posix_getpid()]);
        },
    ),
);

exit($server->run());
