InitPHP Logger

Logger class in accordance with PSR-3 standards

Features

• Keeping logs to the database with PDO.
• Printing log records to a file.
• Logging feature with multiple drivers.

Requirements

• PHP 5.6 or higher
• PSR-3 Interface Package
• PDO Extension (Only PDOLogger)

Installation

composer require initphp/logger

Using

FileLogger

require_once "vendor/autoload.php";
use \InitPHP\Logger\Logger;
use \InitPHP\Logger\FileLogger;

$logFile = __DIR__ . '/logfile.log';

$logger = new Logger(new FileLogger(['path' => $logFile]));

PdoLogger

require_once "vendor/autoload.php";
use \InitPHP\Logger\Logger;
use \InitPHP\Logger\PDOLogger;

$table = 'logs';
$pdo = new \PDO('mysql:dbname=project;host=localhost', 'root', '');

$logger = new Logger(new PDOLogger(['pdo' => $pdo, 'table' => $table]));

$logger->error('User {user} caused an error.', array('user' => 'muhametsafak'));
// INSERT INTO logs (level, message, date) VALUES ('ERROR', 'User muhametsafak caused an error.', '2022-03-11 13:05:45')

You can use the following SQL statement to create a sample MySQL table.

CREATE TABLE `logs` (
    `level` ENUM('EMERGENCY','ALERT','CRITICAL','ERROR','WARNING','NOTICE','INFO','DEBUG') NOT NULL,
    `message` TEXT NOT NULL,
    `date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE = InnoDB CHARSET=utf8mb4 COLLATE utf8mb4_general_ci;

Multi Logger

require_once "vendor/autoload.php";
use \InitPHP\Logger\Logger;
use \InitPHP\Logger\PDOLogger;
use \InitPHP\Logger\FileLogger;

$logFile = __DIR__ . '/logfile.log';

$table = 'logs';
$pdo = new \PDO('mysql:dbname=project;host=localhost', 'root', '');

$logger = new Logger(new FileLogger(['path' => $logFile]), new PDOLogger(['pdo' => $pdo, 'table' => $table]));

Methods

public function emergency(string $msg, array $context = array()): void;

public function alert(string $msg, array $context = array()): void;

public function critical(string $msg, array $context = array()): void;

public function error(string $msg, array $context = array()): void;

public function warning(string $msg, array $context = array()): void;

public function notice(string $msg, array $context = array()): void;

public function info(string $msg, array $context = array()): void;

public function debug(string $msg, array $context = array()): void;

public function log(string $level, string $msg, array $context = array()): void;

All of the above methods are used the same way, except for the log() method. You can use the log() method for your own custom error levels.

Example 1 :

$logger->emergency("Something went wrong");

It prints an output like this to the log file.

2021-09-29T13:34:47+02:00 [EMERGENCY] Something went wrong

Example 2:

$logger->error("User {username} caused an error.", ["username" => "john"]);

It prints an output like this to the log file.

2021-09-29T13:34:47+02:00 [ERROR] User john caused an error.

That is all.
