+[![Latest Stable Version](http://poser.pugx.org/initphp/logger/v)](https://packagist.org/packages/initphp/logger) [![Total Downloads](http://poser.pugx.org/initphp/logger/downloads)](https://packagist.org/packages/initphp/logger) [![Latest Unstable Version](http://poser.pugx.org/initphp/logger/v/unstable)](https://packagist.org/packages/initphp/logger) [![License](http://poser.pugx.org/initphp/logger/license)](https://packagist.org/packages/initphp/logger) [![PHP Version Require](http://poser.pugx.org/initphp/logger/require/php)](https://packagist.org/packages/initphp/logger)
+
+## 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](https://www.php-fig.org/psr/psr-3/)
+- PDO Extension (Only `PDOLogger`)
+
+## Installation
+
+```
+composer require initphp/logger
+```
+
+## Using
+
+### FileLogger
+
+```php 
+require_once "vendor/autoload.php";
+use \InitPHP\Logger\Logger;
+use \InitPHP\Logger\FileLogger;
+
+$logFile = __DIR__ . '/logfile.log';
+
+$logger = new Logger(new FileLogger($logFile));
+```
+
+### PdoLogger
+
+```php 
+require_once "vendor/autoload.php";
+use \InitPHP\Logger\Logger;
+use \InitPHP\Logger\PDOLogger;
+
+$table = 'logs';
+$pdo = new \PDO('mysql:dbname=project;host=localhost', 'root', '');
+
+$logger = new Logger(new PDOLogger($pdo, $table));
+
+$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.
+
+```sql 
+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
+
+```php 
+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($logFile), new PDOLogger($pdo, $table));
+```
+
+## Methods
+
+```php
+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 $context = array()): void;
+```
+
+All of the above methods are used the same way, except for the `log()` method. You can use the `log()` method for your own custom error levels.
+
+**Example 1 :**
+
+```php
+$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:**
+
+```php
+$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.
+
