• Can track separate (or combined) keys. Known as a "section" and an "item"
• AutoRotateFileLogger supports log rotation based on file size (kilobytes) or age (hours) and maximum number of files.
• Uses exclusive locking to lock filed for writing

Simple logging to a file

require '../vendor/autoload.php'

$logger->debug('A debug message');
$logger->info('An information message');
$logger->warn('A warning message');
$logger->error('A fatal error');

$rs = $query->execute();
foreach( $rs as $key => $item ) {
