README

Custom logger package for PHP applications with opinionated log levels.

Usage

There will always be output to stdout. If Open Telemetry is configured, it will be pushed there to.

Basic usage:

$log = new CustomLogger('my-app-name');
$log->otlpHttpHost = 'http://localhost:4318';
$log->info('Something happened', ['key' => 'value']);

Usage with spans

$log = new CustomLogger('auth-4');
$log->otlpHttpHost = 'http://localhost:4318';

$requestSpan = $log->createSpanLogger('request', ['requestId' => 'Legodalf']);

$requestSpan->verbose('Incoming request', ['method' => 'POST', 'path' => '/auth/password']);

$loginSpan = $requestSpan->createSpanLogger('login', ['username' => 'siv']);

$loginSpan->info('User is trying to login');
$userId = User::login('siv');
$loginSpan->verbose('User is logged in');

$loginSpan->endSpan();

$requestSpan->debug('Request is over');

$requestSpan->endSpan();

Log levels

• error: Apocalypse! :O
• warning: The chaos is near
• info: All is well, but this message is important
• verbose: Extra info, likely good in a production environment
• debug: A lot of detailed logs to debug your application [default]

Log formats

• json: Outputs a string of a JSON object
• text: Outputs a simple string [default]

Open Telemetry Collector endpoint

A DSN string, example: 'http://localhost:4318'. The target must be a protobuf endpoint.

Local development

Either register an auto loader, or explicitly require all PHP-files in this repo, and then just start using and developing.

Running tests

composer install
composer test

Or invoke PHPUnit directly: vendor/bin/phpunit.
