我已經在我的服務器上安裝了 MongoDB，我正在嘗試運行這個腳本：<?php$client = new MongoClient();$collection = $client->cryptnote->storedMessages;function insertDocument($collection, $id, $telegramuser, $message) {    $doc = array(        "id" => $id,        "telegram" => $telegramuser,        "encrypted" => $message,    );    try {        $collection->insert($doc);    } catch(Exception $e) {        echo "Error" . $e;    }}function findDocument($collection, $id){    return $collection->findOne(["id" => $id]);}insertDocument($collection, "test123", "usertest", "message. test.");$query = findDocument($collection, "test123");echo "<pre>";var_dump($query);這是我得到的錯誤： Got error 'PHP message: PHP Fatal error:  Uncaught Error: Class 'MongoClient' not found in /var/www/html/dbtest.php:5我的 Apache 服務器使用/etc/php/7.3/fpm/php.ini根據phpinfo();.添加extension=mongodb.so到php.ini文件是沒有用的。
