README

A simple PSR-3 logger using PHP's error_log function.

Installation

composer require celemas/log

Usage

Create a logger without arguments to write to PHP's default SAPI error logger.

use Celemas\Log\Logger;

$logger = new Logger();
$logger->info('Application started');

See the documentation for file logging, level filtering, and formatter usage.

Testing

During testing, PHP's error_log ini setting is set to a temporary file. To print the output to the console, prepend a special env variable to the PHPUnit cli command, as follows:

ECHO_LOG=1 phpunit

Test Environment Requirements

Tests require:

• ini_set() function enabled (for error_log redirection)
• Writable system temp directory (for test log file isolation)
• PHP error_reporting must be modifiable

These are standard in development environments but may fail in restricted PHP configurations where ini_set is disabled via disable_functions.
