If you are using MySQL on a non-standard port, you can use the "hostname:port" syntax, for example  . Note that using a port number when you specify  as the host name will have no effect, as MySQL will connect through a socket instead. If the MySQL server is on the same server and you want to connect through a socket in a non-standard location, you can use the "localhost:socket" location, for example  . Currently it's not possible to specify a custom location when connecting through socket when PHP is using the new MySQLi extensions.
