Codeigniter 4 custom log levels

After some more tinkering, I found a way to override handler config for specified logging level to allow custom file extension and save path.
Extended logger->log() method with AufitLogger->customLog() method as follows. This may be hacky, but it appears to work.


app/Log/AuditLogger

PHP Code:

public function customLog($level, string|Stringable $message, array $context = []): void
    {
        if ($level === 'audit') {

            // assuming the first or the only handler is the correct one (FileHandler in our case)
            $handlerClassName = array_keys($this->handlerConfig)[0];
            $savePath = WRITEPATH . 'custom_logs/';

            $this->handlerConfig[$handlerClassName]['fileExtension'] = 'tmp';
            $this->handlerConfig[$handlerClassName]['path'] = $savePath;

            // re-initialize handler with changed config
            $this->handlers[$handlerClassName] = new $handlerClassName($this->handlerConfig[$handlerClassName]);
            
            // run parent log() method with updated handler
            parent::log($level, $message, $context);
        }
    }
