## 安装
`composer require monolog/monolog`
## 使用
```
date_default_timezone_set('RPC');
use Monolog\Formatter\LineFormatter;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
use Monolog\Handler\FirePHPHandler;
$dateFormat = "Y-m-d H:i:s";
// 默认的输出格式是 "[%datetime%] %channel%.%level_name%: %message% %context% %extra%\n"
$output = "[%datetime%] %channel%.%level_name%: %message% %context% %extra%\n";
// 最后创建一个格式化器
$formatter = new LineFormatter($output, $dateFormat);
// 创建一些处理器
$stream = new StreamHandler(__DIR__.'/my_app.log', Logger::DEBUG);
$firephp = new FirePHPHandler();
$stream->setFormatter($formatter);
// 创建应用的主要日志服务实例
$logger = new Logger('my_logger');
$logger->pushHandler($stream);
$logger->pushHandler($firephp);
/*设置扩展 %extra% 的值*/
$logger->pushProcessor(function ($record) {
$record['extra']['dummy'] = 'Hello world!';
return $record;
});
$logger->info("this is a info",['name'=>'asd']);
//[2019 10 17, 2:31 am] my_logger.INFO: this is a info {"name":"asd"} {"dummy":"Hello world!"}
// 使用另外的通道来创建安全相关的日志服务示例
$securityLogger = new Logger('security');
$securityLogger->pushHandler($stream);
$securityLogger->pushHandler($firephp);
// 或者克隆第一个，只是改变下通道
$securityLogger = $logger->withName('security');
$securityLogger->info("this is a security");
//[2019 10 17, 2:31 am] security.INFO: this is a security [] {"dummy":"Hello world!"}
