{
    switch (
$module) {
        case 
MongoLog::RS: return "REPLSET";
        case 
MongoLog::CON: return "CON";
        case 
MongoLog::IO: return "IO";
        case 
MongoLog::SERVER: return "SERVER";
        case 
MongoLog::PARSE: return "PARSE";
        default: return 
"UNKNOWN";
    }
}

function 
level2string($level)
{
    switch (
$level) {
        case 
MongoLog::WARNING: return "WARN";
        case 
MongoLog::INFO: return "INFO";
        case

}

function 
callback($module$level$message)
{
    echo 
date("Y-m-d H:i:s - ");
    
printf("%s (%s): %s\n"module2string($module), level2string($level), $message);
}

MongoLog::setLevel(MongoLog::ALL);
MongoLog::setModule(MongoLog::ALL);

// Мы указываем здесь имя функции, но любая вызываемая функция (например, анонимная функция) будет работать
MongoLog::setCallback("callback");
