README
This package provides a flexible PSR-3 compliant logging solution for your PHP application. It includes a logger with support for all PSR-3 log levels and optional logging to custom files or falling back to error_log()
when no log file is provided.
Features
- PSR-3 Compliant: Supports all PSR-3 log levels (
emergency
,alert
,critical
,error
,warning
,notice
,info
,debug
). - File Logging: Logs to a specified file, automatically creating the file and necessary directories if they do not exist.
- Fallback to
error_log()
: If no log file is specified, the package will fall back to PHP’s built-inerror_log()
. - Easy Setup and Use: A simple static interface (
Log
) to use in your application.
Installation
To install the package, you can use Composer:
composer require devuri/logger
Make sure to include Composer's autoloader in your project:
require 'vendor/autoload.php';
Usage
Initialization
You can initialize the logger by specifying a log file. If no file is provided, it will fall back to error_log()
.
use Urisoft\Log; use Urisoft\FileLogger; // Initialize the logger with a custom log file $logFile = __DIR__ . '/logs/app.log'; Log::init(new FileLogger($logFile));
Logging Messages
You can log messages at various levels using the following methods:
// Log an informational message Log::info('Application started successfully.'); // Log an error with context (PSR-3 interpolation) Log::error('Error occurred: {error}', ['error' => 'Database connection failed']); // Log a warning message Log::warning('Low disk space warning.'); // Log a critical error Log::critical('Critical issue encountered in payment processing.');
Log Levels
The package supports the following log levels:
Log::emergency($message, $context = [])
Log::alert($message, $context = [])
Log::critical($message, $context = [])
Log::error($message, $context = [])
Log::warning($message, $context = [])
Log::notice($message, $context = [])
Log::info($message, $context = [])
Log::debug($message, $context = [])
Creating the Log File Automatically
If the log file or its directories do not exist, the logger will create them automatically:
use Urisoft\Log; use Urisoft\FileLogger; $logFile = __DIR__ . '/logs/application.log'; Log::init(new FileLogger($logFile)); Log::info('Logging system initialized.');
Configuration
Custom error_log()
If no log file is provided, the package will fall back to using PHP’s error_log()
function. You can configure where error_log()
writes by setting the error_log
directive in your php.ini
or using ini_set()
:
// Redirect error_log to a custom file ini_set('error_log', __DIR__ . '/logs/error.log'); // Initialize logger without a file to fallback to error_log Log::init(new FileLogger());

Additional Notes:
- Error Handling: If the logger cannot create the log file or write to the specified location, it will throw a
RuntimeException
with a relevant message. - Log Rotation: This package does not include log rotation functionality by default, so you may want to use external tools or another package to handle log rotation.
