Monolog sends your logs to files, sockets, inboxes, databases and various
web services. See the complete list of handlers below. Special handlers
allow you to build advanced logging strategies.
This library implements the PSR-3
interface that you can type-hint against in your own libraries to keep
a maximum of interoperability. You can also use it in your applications to
make sure you can always use another compatible logger at a later time.
As of 1.11.0 Monolog public APIs will also accept PSR-3 log levels.
Internally Monolog still uses its own level scheme since it predates PSR-3.
Install the latest version with
$ composer require monolog/monolog
<?php use Monolog\Logger; use Monolog\Handler\StreamHandler; // create a log channel $log = new Logger('name'); $log->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING)); // add records to the log $log->warning('Foo'); $log->error('Bar');
Tidelift delivers commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use.
Third party handlers, formatters and processors are
listed in the wiki. You
can also add your own there if you publish one.
^2.0works with PHP 7.2 or above, use Monolog
