When making the calculations for the filename of the current month using
date('d') does not work because you may run into the situation where you run
the tests on a day in a month that does not exist in the previous month,
for example March 30th. As there is no February 30th, PHP will skip ahead
to March, and the filename for the "previous" month will incorrectly be
"2017-03" instead of the expected "2017-02". Using the first day of the
month instead of the current day of the month solves this problem.
For consistency we now also use the first month of each year for calculations
regarding years even if this is not necessary, it would break symmetry
if we don't, plus it makes it clear that the value is not relevant in the
calculation.
Monolog - Logging for PHP 
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.
Installation
Install the latest version with
$ composer require monolog/monolog
Basic Usage
<?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->addWarning('Foo');
$log->addError('Bar');
