Host and Port connection

[Mitch Q]

Hi Team, 

I've been trying to setup the database connection to use the following details:

host => '127.0.0.1'

port => xxxx (non-default)

SETUP 1:

using host => localhost disregards the non-default port

SETUP 2:

using host => 127.0.0.1 regardless of port, results to "Please check your database connection in `app/Config/database.php` or may be some syntax error."

SETUP 3:

using host=> 127.0.0.1:XXXX results the same with SETUP 2

SETUP 4:

using host => localhost:XXXX results the same with Database Configuration form. 

Is it possible to use a non-default port and and host other than 'localhost'. Already checked the credentials and privileges and connections are okay when using different mysql client tool.  

Thank you very much in advance!
