unknown mysql server host 127.0.0.1:90 error ... how to connect when not on port 80

[shembrut]

I have IIS and Apache installed on the same box. IIS is listening to port 80 and I have apache configured to listen to port 90.

When I try to connect to the MySQL database using mysqli_connect I keep getting the error 'Unknown MySQL server host 127.0.0.1:90.

This is what my connection string looks like:

mysqli_connect ("127.0.0.1:90", "root", "pass", "prodDB", "3306")

I also changed my php.ini to set the mysqli.default_host = 127.0.0.1:90

Any ideas?
