您好我正在尝试mongo DB(Version 3.4.18)使用连接CakePHP (version 3.5.1) with Apache server on PHP (7.2.4)并面临以下错误

对于 mongo db 连接尝试下面的代码

public function __connectmongodb()
{

    $m = new \MongoClient('mongodb://localhost:27017');
    return $db = $m->myDb;
}

注意：我必须在mongo DB(Version 3.4.18)使用CakePHP (version 3.5.1) with Apache server on PHP (7.2.4)这些特定版本时这样做

更新- 我们尝试使用php_mongodb-1.4.0-7.2-ts-vc15-x64这个 .dll 文件在 Windows 上

php_mongodb-1.4.0-7.2-ts-vc15-x64是“新”或更确切地说是唯一官方支持的驱动程序https://pecl.php.net/package/mongodb。它的用法记录在这里https://www.php.net/manual/en/set.mongodb.php并且基本上是使用MongoDB\Driver\Manager.

这MongoClient是来自旧版和很久以前弃用的驱动程序：https ://pecl.php.net/package/mongo 。它记录在这里https://www.php.net/manual/en/book.mongo.php

PHP 7 的旧版驱动程序没有官方支持：https ://jira.mongodb.org/browse/PHP-1474

上次旧版驱动程序于2018 年 2 月在https://docs.mongodb.com/ecosystem/drivers/php/上列出。到那时，它声称与 mongodb server v2.4、v2.6 和 v3.0 兼容，与数据库 v3.2+ 不兼容。

同样的 2018 年 2 月 mongodb v3.0 退役。对 Mongodb v3.2 的支持已在 2018 年晚些时候停止，v3.4 正在计算其最后几个月的支持，直到 2020 年 1 月。

长话短说，不，您实际上并不希望使用MongoClient.
