connect to sql with port number

[tippet5x]

hello
my dba moved the backend sql and now I’m having issues connection.
MY old php script that poked the database to verify it was there:

<?php $DBinstance01 = "IT-DB24.abc.com\IT"; $DBcon01 = array("Database"=>"webester", "UID"=>"webuserid", "PWD" => "webpass"); Now I need to add a port to the first line but its not working $DBinstance01 = "IT-DB24.abc.com\IT", 54652; is my syntax incorrect when adding the port number?
