SLogger

A Simple Logger class for PhP.

About

This is a simple Logger class meant to be easy to implement so that you don't have to worry about to much configuration. This class follow a PSR-3 standard.

Basic Usage

The minimum setup needed to use the Logger class.

<?php
require_once("vendor/Autoloader.php");

use Kuran\SLOGGER\{Logger, ErrorLevel, Managers\FileManager};

/* Instanciate the Logger.
*  Add a Manager to the logger. The manager has a default Formater.
*/
$log = new Logger(
    array(
        new FileManager()
        )
    );


/* Simple log.
*  Needs a message body, and an array for context.
*/
$log->alert(
    "Test message for the file {:file}",
    array(
        ":file" => __FILE__,
        ":extras" => array(
            ["name" => "Admin", "username" => "admin"],
            ["name" => "Root", "username" => "root"]
            )
    )
);

Logger class options

- _Constructor_

| Argument | Description | | -------- | ------------------------------------------ | | managers | set an array of managers at instanciation. |

    __construct(array $managers = array())

Same as creating a logger without argument then using the _setManagers()_ function

- _setManagers method_

This method is used to set an array of managers to the logger. This will replace the Logger's managers list.

    setManagers(array $managers);

Many managers can be used to log messages to different files, or using different methods (Database...). Or to log messages with different Error Levels.

- _addManager method_

This method is used to add a simgle manager to the managers stack. If you want to add another _Manager_ later in your code.

    addManager(ManagerInterface $manager);

FileManager options

- _Constructor_

all arguments are optional. | Argument | Description | |----------|------------------------------------------------------------------------------------------| | filePath | If no filepath is defined, it will log message to _app.log_ by default | | level | Default level is _ErrorLevel::ERROR_ | | formater | If no Formater is defined, it will default to a _LineFormater_ with default options. |

__construct(
        string $filePath = 'app.log',
        ErrorLevel $level = ErrorLevel::ERROR,
        FormaterInterface $formater = null)

- _setFormater_

used to replace the Formater already in place.

    setFormater(FormaterInterface $formater)

Usage

    $manager = new FileManager(
        filePath: "path/to/logfile.log",
        level: ErrorLevel::INFO, // Set the minimum Error level for this manager.
        formater: new LineFormater()
    )

    // Setting multiple managers with different Error Levels

    $log = new Logger();

    $errorManager = new FileManager(
        filePath: "error.log",
        level: ErrorLevel::ERROR
    );
    $debugManager = new FileManager(
        filePath: "debug.log",
        level: ErrorLevel::DEBUG
    );

    //set the Manager list to $errorManager and $debugManager
    $log->setManager(array($errorManager, $debugManager));

    // add $manager to the list of managers
    $log->addManager($manager);

Error Levels

The Error levels are defined as follow in the _ErrorLevel_ enum

enum ErrorLevel: int
{
    case EMERGENCY = 800; //ErrorLevel::EMERGENCY
    case ALERT     = 700; //ErrorLevel::ALERT
    case CRITICAL  = 600; //ErrorLevel::CRITIAL
    case ERROR     = 500; //ErrorLevel::ERROR
    case WARNING   = 400; //ErrorLevel::WARNING
    case NOTICE    = 300; //ErrorLevel::NOTICE
    case INFO      = 200; //ErrorLevel::INFO
    case DEBUG     = 100; //ErrorLevel::DEBUG
}

    __construct(
        string $format = null,
        string $timeFormat = null
        )
