范例

Example #1 MongoLog::setCallback() example

<?phpfunction 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);// We specify the function name here, but any callable (e.g. anonymous function) will workMongoLog::setCallback("callback");new MongoClient();?>

以上例程的输出类似于:
