LogStream PHP SDK

PHP SDK for LogStream — a self-hosted log aggregator inspired by Papertrail.

Sends your application logs to your LogStream instance in real time. Works with any PHP project — no framework required.

Requirements

• PHP 7.2+
• cURL extension enabled
• A running LogStream instance

Installation

composer require logstream/laravel-sdk

Standalone usage (any PHP project)

Zero dependencies. Works with pure PHP 7.2+.

use LogStream\LogStreamClient;

$log = new LogStreamClient(
    'https://your-logstream.com',
    'src_your_token_here',
    'my-app',        // source
    'production'     // environment
);

$log->info('User authenticated', ['user_id' => 42]);
$log->warning('Rate limit reached', ['requests' => 480]);
$log->error('Payment failed', ['order_id' => 99]);
$log->debug('Query executed', ['time_ms' => 12]);

Available methods: debug, info, notice, warning, error, critical, alert, emergency.

Or use the generic method:

$log->log('error', 'Something went wrong', ['code' => 500]);

Constructor parameters

Laravel integration

Uses Laravel's custom driver with a Monolog handler internally. No extra packages needed — Monolog is already part of Laravel.

1. Add the channel to config/logging.php

use LogStream\Laravel\LogStreamChannel;

'channels' => [

    'logstream' => [
        'driver' => 'custom',
        'via'    => LogStreamChannel::class,
        'url'    => env('LOGSTREAM_URL'),
        'token'  => env('LOGSTREAM_TOKEN'),
        'source' => env('LOGSTREAM_SOURCE', 'my-app'),
    ],

    // To log both locally and to LogStream at the same time:
    'stack' => [
        'driver'   => 'stack',
        'channels' => ['daily', 'logstream'],
    ],

],

2. Add to .env

LOG_CHANNEL=stack

LOGSTREAM_URL=https://your-logstream.com
LOGSTREAM_TOKEN=src_your_token_here
LOGSTREAM_SOURCE=my-app-name

The token is generated in the LogStream dashboard under Sources → Create Source.

3. Use normally

All Log::* calls are forwarded to LogStream automatically:

Log::info('User authenticated', ['user_id' => 42]);
Log::error('Payment failed', ['order_id' => 99]);

// Or send only to LogStream:
Log::channel('logstream')->warning('Rate limit reached');

PSR-3 usage

For projects that require a Psr\Log\LoggerInterface (e.g. dependency injection containers, third-party libraries), install psr/log first:

composer require psr/log

Then wrap the client:

use LogStream\LogStreamClient;
use LogStream\Logger\LogStreamLogger;

$client = new LogStreamClient('https://your-logstream.com', 'src_token', 'my-app');
$logger = new LogStreamLogger($client);

// $logger now implements Psr\Log\LoggerInterface
$logger->info('Hello', ['user_id' => 1]);

Useful when injecting the logger into a class that depends on the interface:

class PaymentService
{
    public function __construct(private \Psr\Log\LoggerInterface $logger) {}

    public function process(int $orderId): void
    {
        $this->logger->info('Processing payment', ['order_id' => $orderId]);
    }
}

$service = new PaymentService(new LogStreamLogger($client));

Error handling

All errors during log delivery (network failures, timeouts, invalid responses) are silently swallowed. Logging will never crash your application.
