How to use Monolog with CakePHP?

CakePHP is a popular PHP framework that provides rich features and components that allow developers to easily build web applications. Monolog is a powerful logging tool that can help developers record events and errors that occur in applications, providing a variety of output and processing methods. This article will introduce how to use Monolog with CakePHP.

1. Install Monolog

Install Monolog through Composer:

composer require monolog/monolog

2. Configure Monolog

In config/bootstrap .php, add the following code to configure Monolog:

use MonologLogger;
use MonologHandlerStreamHandler;

$log = new Logger('name');
$log->pushHandler(new StreamHandler(LOGS . 'debug.log', Logger::DEBUG));
Log::setLogger($log);

This configuration sets Monolog as CakePHP’s default logger and sets the log level to DEBUG. Logs will be recorded in the app/logs/debug.log file.

3. Logging

Logging in the application is very simple. You only need to pass the information to be recorded as a string to the Log class:

use CakeLogLog;

Log::info('This is an information message.');

The Log class has multiple static methods that can be used for different log levels:

Log::emergency($message);
Log::alert($message);
Log::critical($message);
Log::error($message);
Log::warning($message);
Log::notice($message);
Log::info($message);
Log::debug($message);

4. Add other processors

Monolog supports a variety of processors (handlers), which can log Output to different locations. For example, you can log to a file and syslog:

use MonologHandlerSyslogHandler;

$log = new Logger('name');
$log->pushHandler(new StreamHandler(LOGS . 'debug.log', Logger::DEBUG));
$log->pushHandler(new SyslogHandler('myapp', LOG_USER, Logger::WARNING));
Log::setLogger($log);

This configuration logs to the app/logs/debug.log file and the system log (LOG_USER). Information with a log level of WARNING or above will be recorded in the system log.

5. Using other features of Monolog

Monolog provides many other features, such as handler stack, exception handling, logging context, etc. Please refer to Monolog's documentation for details.
