Database Connectivity

Question

I wrote it according to your code, but I got an error when accessing it.

Isn’t it necessary to fill in the database connection account and password here?

Answer 1

mysqli_connect($localhost,$username,$password,$dbname,$port);

This is also possible

Answer 2

You can share your error report and take a look. It may also be that you forgot to set the password when creating the database connection in the database
