Warning: mysqli_connect(): Unknown MySQL server host

Question

I have some trouble connecting to a mysql server. I can connect using the linux terminal, so I know that my host, port, user, and password works. I cannot, however, connect

Answer 1

The host parameter in the mysql function need to be "localhost" or "127.0.0.1"

You set the parameter as "host:port" and that is your mistake. It's need to be the full alias of the network in the server or the remote server with the full IP address.
