php What should I do if PDO fails to import the database?

An error message is displayed indicating that you have connected to the database fine, but the project database has not been selected yet.

To be sure it's trying to correct with the correct DSN, I would try changing the connection string to contain the value directly instead of a variable, ie:

'mysql:host=localhost;dbname=project'
Copy after login

This shouldn't make a difference, but is worth checking .

If that doesn't work, and since you seem to be able to connect to MySQL,

The workaround might be to include the database name as part of the query.

So your query above will become:

$query=$dbh->prepare("INSERT INTO project.users (userName, userEmail) VALUES (?,?)");
Copy after login
