您好，我正在尝试使用 CakePHP (version 3.5.1) with Apache server on PHP (7.2.4) 连接 mongo DB(Version 3.4.18) 并遇到以下错误

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) 中使用 CakePHP (version 3.5.1) with Apache server on PHP (7.2.4) 这些特定版本进行此操作
更新 - 我们在 Windows 上尝试使用 php_mongodb-1.4.0-7.2-ts-vc15-x64 这个 .dll 文件
【问题讨论】：
-
您是否安装了 MongoDB 的驱动程序并包含在您的 php 中？
-
不，实际上我们希望使用 MongoClient 而不是 MongoDB\Driver\Manager
-
当然可以，但是 PHP 需要驱动才能连接到 MongoDB。不管你想使用什么连接器，它们都需要驱动程序（Windows 上的 .dll 和 *nix 上的 .so）
-
我们使用
php_mongodb-1.4.0-7.2-ts-vc15-x64这个.dll文件在windows上尝试
