README

This project is a detached fork of APIx Log as I wanted to add features and bug fixes not available in the original version.

Minimalist and fast PSR-3 compliant logger.

Light, come out-of-the-box bundle with wrappers for:
- ErrorLog, File, Mail, Sapi ~ built around the error_log() function,
- Runtime ~ as an Array/ArrayObject wrapper, and Nil ~ as Null wrapper,
- Stream ~ logs are sent to sockets, local and remote files, filters and other similar resources (default to standard output bypassing output buffering).
Extendable, additional logging backends are available:
- PHPMailer/apix-log-phpmailer ~ logs are sent using PHPMailer,
- jspalink/apix-log-pushover ~ logs are sent using Pushover,
- apix/log-tracker ~ adds logger/tracker such as Google Analytics, Dashbot, etc...,
Very fast and even faster when logging is deferred. See here on how it compares to monolog
Clean API, see the LoggerInterface and the FormatInterface.
100% Unit tested and compliant with PSR0, PSR1 and PSR2.

Installation

  composer require 8ctopus/apix-log

Basic usage

This simple logger is set to intercept all logs and display them in the console.

$console = (new Apix\Log\Logger\Stream('php://stdout'))
   ->setMinLevel('debug')
   ->setFormat(new Apix\Log\Format\ConsoleColors())
   ->notice('Running out of {items}', 'Running out of {items} - left {left}', [
      'items' => 'beers',
      'left' => 5,
   ]);

[2023-03-20 08:01:25] NOTICE Running out of beers - left 5

Advanced usage ~ multi-logs dispatcher

Let's create an additional logger with purpose of catching log entries that have a severity level of warning or more.
See the log levels for the order.

$file = (new Apix\Log\Logger\File(__DIR__ . '/app.log'))
   // intercept logs that are >= `warning`
   ->setMinLevel('warning')
   // propagate to other loggers
   ->setCascading(true)
   // postpone writing logs to file
   ->setDeferred(true)
   // flush logs to file once 100 logs are collected
   ->setDeferredTrigger(100);

setCascading() set to true (default: true) so the entries caught here continue downstream past that particular logger.\
setDeferred() was set to true (default: false) so processing happens when:
- setDeferredTrigger is reached
- flushDeferredLogs is called
- __destruct (end of script generally)

Now, let's create a main logger object and inject the two previous loggers.

$logger = new Apix\Log\Logger([$console, $file]);

Finally, let's push some log entries:

$exception = new \Exception('Boo!');

// handled by all loggers
$logger->critical('OMG saw {bad-exception}', ['bad-exception' => $exception]);

// push an object (or array) directly
$logger->error($exception);

// handled by console logger
$logger->info('Testing a var {my_var}', ['my_var' => [...]]);

compare only log entry vs master branch
fix demo colors in branch only log entry if faster
should Logger inherit from AbstractLogger?
add html formatting for emails
change context logging
add log line?
