A project written by Paul Coifier .

Liberta-Logger is an easy-to-use PSR-3 compliant logging class for PHP. It isn't naive about file permissions (which is expected). It was meant to be a class that you could quickly include into a project and have working right away.

If you need a logger that supports PHP < 5.3.

From the Command Line:

composer require liberta\logger:dev-master

In your composer.json:

{
    "require": {
        "liberta/logger": "dev-master"
    }
}

<?php

require 'vendor/autoload.php';

$users = [
    [
        'name' => 'Paul Coiffier',
        'username' => 'pcoiffier',
    ],
    [
        'name' => 'Audrey Dupont',
        'username' => 'adupont',
    ],
];

$logger = new Liberta\Logger\Logger(__DIR__.'/logs');
$logger->info('Returned a million search results');
$logger->error('Oh dear.');
$logger->debug('Got these users from the Database.', $users);

[2014-03-20 3:35:43.762437] [INFO] Returned a million search results
[2014-03-20 3:35:43.762578] [ERROR] Oh dear.
[2014-03-20 3:35:43.762795] [DEBUG] Got these users from the Database.
    0: array(
        'name' => 'Paul Coiffier',
        'username' => 'coiffierp',
    )
    1: array(
        'name' => 'Michel Dupont',
        'username' => 'mdup',
    )

Liberta-Logger is PSR-3 compliant. This means it implements the Psr\Log\LoggerInterface.

See Here for the interface definition.

You can use the Psr\Log\LogLevel constants to set Log Level Threshold, so that any messages below that level, will not be logged.

The default level is DEBUG, which means everything will be logged.

<?php
use Psr\Log\LogLevel;

// These are in order of highest priority to lowest.
LogLevel::EMERGENCY;
LogLevel::ALERT;
LogLevel::CRITICAL;
LogLevel::ERROR;
LogLevel::WARNING;
LogLevel::NOTICE;
LogLevel::INFO;
LogLevel::DEBUG;

<?php
// The 
$logger = new Liberta\Logger\Logger('/var/log/', Psr\Log\LogLevel::WARNING);
$logger->error('Uh Oh!'); // Will be logged
$logger->info('Something Happened Here'); // Will be NOT logged

MLogger supports additional options via third parameter in the constructor:

<?php
// Example
$logger = new Liberta\Llogger\Logger('/var/log/', Psr\Log\LogLevel::WARNING, array (
    'extension' => 'log', // changes the log file extension
));
