• pattern based logfile path: /{TYPE}/{YEAR}/{YEAR}-{MONTH}/{TYPE}-{MONTH}-{DAY}
• pattern based rows: {DATE} | {STATUS} --- {MESSAGE}
• objects and arrays converted to prettified JSON automatically
• customizable CSV row pattern: '"{DATE}";{MESSAGE};"{BACKTRACE.CLASS}";"{BACKTRACE.FUNCTION}"'
• multiple log types in config

Available log levels

• Log::to()->info($message, $title = null);
• Log::to()->error($message, $title = null);
• Log::to()->critical($message, $title = null);

                - /ERROR-2022-10-22.log

Use default config

    use Schalkt\Slog\Log;

    require_once '/vendor/autoload.php';

    Log::to()->info('Hello World!');

Change default log folder

    use Schalkt\Slog\Log;

    require_once '/vendor/autoload.php';

    Log::default(["folder" => APP_PATH . '/storage/logs/default']);
    Log::to()->info('Hello World!');

Add new config

    use Schalkt\Slog\Log;

    require_once '/vendor/autoload.php';

    Log::config('import', [
        'folder' => APP_PATH . '/storage/logs/import',
        'folder_chmod' => 0700,
        'pattern_row' => '{DATE} {EOL} {STATUS} {EOL} {MESSAGE} {EOL} {REQUEST}',
    ]);

    // add an error to the import log
    Log::to('import')->error('Unique id required');

Load custom configs from file

    use Schalkt\Slog\Log;

    require_once '/vendor/autoload.php';

    // set config file path
    Log::configs('./config/logs.php');

    // add an error to the default log
    Log::to()->error('Password required');

    // add an input array to the login log with title
    Log::to('login')->notice($input, 'Invalid password');
