テストプログラム

パッケージのテストフォルダ(test\)に、テスト用のコード(monolog.php)を作成し実行します。以下の例では、test\logs\app.log にログファイルが出力されます。

monolog.php

<?php
require __DIR__.'/../vendor/autoload.php';
 
use Monolog\Logger;
use Monolog\Formatter\LineFormatter;
use Monolog\Handler\StreamHandler;
 
// monologの初期化 ////////////////////////
$log = new Logger('APRICOT');
 
// ログチャネルの作成  ////////////////////////
$log_path = 'logs/app.log';
$log_level = Logger::DEBUG;
$stream = new StreamHandler($log_path, $log_level);
$log->pushHandler($stream);
 
// ログフォーマット設定
// ログ内の改行を許可、付加情報が空の場合無視する
$stream->setFormatter(new LineFormatter(null, null, true, true));
 
// ログ出力 ///////////////////////////////
$log->error('Errorメッセージ');
$log->warning('Warningメッセージ');
$log->info('Infoメッセージ');
$log->debug('Debugメッセージ');
 
echo 'Hello Monolog!';

結果
