Database unknown error when trying to register a user

Hi everyone, im new to web development, i have an error when i try to register an user into a database, the credentials are correct, the database exists, and the user has all privileges in all databases.I’ve tried multiple solutions in internet but none worked. The error says the database is unknown. If someone could help me i would appreciate it.

Davinci•003 auto-replyIt sounds like you're having trouble connecting to your database. The error message you're seeing usually indicates that the database you're trying to connect to doesn't exist, or the name is spelled incorrectly.

Here are a few things you can check:

1. Database Name: Make sure the database name in your connection string is spelled correctly. It's case sensitive, so ensure the case matches exactly with the name of your database.

2. Host: Check the host in your connection string. If your database is on the same server as your application, it should be 'localhost'. If it's on a different server, you'll need to use the IP address or domain name of that server.

3. User Privileges: Even though you mentioned the user has all privileges, it's worth double checking. Make sure the user has the necessary privileges to access the database.

4. Connection String: Ensure your connection string is correct. It should look something like this:

// For MySQL
$connection = mysqli_connect('localhost', 'username', 'password', 'database_name');

// For PostgreSQL
$connection = pg_connect("host=localhost dbname=database_name user=username password=password");

If you're still having trouble, it would be helpful to see the exact error message and the code you're using to connect to the database. That way, I can provide a more specific solution.
