PDO missing from package software

[Html]

Hi, I got this line 705 from a connection.php file.

Error: Class 'PDO' not found in

        return new $pdoClass($dsn, $this->username, $this->password, $this->attributes);
    }

I tried the official site, nothing on this. The installation was okay. Line 705.

There are instructions for installing PHP with PDO here: https://www.php.net/manual/en/pdo.installation.php

[Html]

So this PDO class is not available on the server I use, and should the package not contain this?

An Error occurred while handling another error:

Here is the error

PDO is a native PHP class, so libraries and frameworks are not going to try to build their own version of it. You need to make sure that PDO is installed along with PHP, if you cannot do that then you cannot use this library.
