About

This class is an improved version of KLogger which I use in my projects and I maintain. (KLogger is an easy-to-use PSR-3 compliant logging class for PHP). It was meant to be a class that you could quickly include into a project and have working right away.

Improvements:

• Stabilisation
• Added format functionality
• Placed all in one class
• Performance improvement

Installation

Composer

From the Command Line:

composer require iulianmironica/klogger:dev-master

In your composer.json:

{
    "require": {
        "iulianmironica/klogger": "dev-master"
    }
}

Basic Usage

<?php

require 'vendor/autoload.php';

$users = [
    [
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    ],
    [
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    ],
];

// New feature
$loggerSettings = [
    'level' => \IulianMironica\KLogger\Logger::DEBUG, // emergency, alert, critical, error, warning, notice, info, debug
    'timestamp' => 'm-d-Y G:i:s', // leave blank for none
    'format' => '%timestamp% %level% %class% %function% %message%', // output format - leave blank for none
    'directory' => /path/to/log/dir, // path to the log directory
    /* %timestamp%      - the timestamp declared above
     * %level%          - level declared above
     * %class%          - class name
     * %function%       - method/function name
     * %message%        - the message passed as param
     * %line%, %file%   - point to the parent file that triggered method/function
     */
];

$logger = new \IulianMironica\KLogger\Logger($loggerSettings);
$logger->info('Returned a million search results');
$logger->error('Oh dear.');
$logger->debug('Got these users from the Database.', $users);

// New feature - you can now debug your data without needing to pass a string as first param
$logger->debug($users);

Output

02-19-2015 14:34:08 DEBUG Model\User getAll Got these users from the Database.
    0: array(
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    )
    1: array(
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    )
02-19-2015 14:34:08 DEBUG Model\User getAll
    0: array(
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    )
    1: array(
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    )

Setting the Log Level Threshold

You can use the \IulianMironica\KLogger\Logger constants to set Log Level Threshold, so that any messages below that level, will not be logged.

Default Level

The default level is DEBUG, which means everything will be logged.

Available Levels

<?php
use IulianMironica\KLogger\Logger;

// These are in order of highest priority to lowest.
\Logger::EMERGENCY;
\Logger::ALERT;
\Logger::CRITICAL;
\Logger::WARNING;
\Logger::NOTICE;
\Logger::INFO;
\Logger::DEBUG;

Example

<?php

$loggerSettings = [
    'level' => \IulianMironica\KLogger\Logger::ERROR, // emergency, alert, critical, error, warning, notice, info, debug
    'timestamp' => 'm-d-Y G:i:s', // leave blank for none
    'format' => '%timestamp% %level% %class% %function% %message%', // output format - leave blank for none
    'directory' => /path/to/log/dir, // path to the log directory
    /* %timestamp%      - the timestamp declared above
     * %level%          - level declared above
     * %class%          - class name
     * %function%       - method/function name
     * %message%        - the message passed as param
     * %line%, %file%   - point to the parent file that triggered method/function
     */
];

$logger = new \IulianMironica\KLogger\Logger($loggerSettings);
$logger->error('Uh Oh!'); // Will be logged
$logger->info('Something Happened Here'); // Will be NOT logged

Why use KLogger?

Why not? Just drop it in and go. If it saves you time and does what you need, go for it! Take a line from the book of our C-code fathers: "build upon the work of others".

Klogger has been used in projects at:

* The University of Iowa
* The University of Laverne
