Additional information

hello @yhangde

When you chose your database driver, did you choose “mysql” or “mysqli”?



Hi @yhangde as the text above it says, if it’s in square brackets it isn’t installed. Use “mysqli” instead.

Thank you for your reply.

As I said at the beginning, my database platform and PHP platform are both installed, but this error still occurs.

At present, the problem has been solved.

The real reason is that a database extension was not installed correctly.Because I installed PHP before installing the database, a PHP extension related to the database was not installed.

The correct order of installation is to install my SQL database first, and then install PHP, so that the relevant PHP extensions will be configured correctly.
