    Примеры

    Пример #1 Пример использования MongoLog::setCallback()

    <?php

    function module2string($module)
    {
        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     MongoLog::FINE: return "FINE";
            default: return     "UNKNOWN";
        }
    }

    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");

    new     MongoClient();
    ?>

    Результатом выполнения данного примера будет что-то подобное:
