How to get vSphere host name rather than host id? - php

Question

I have a script (below) which connects to a vCenter and pulls off all of the VMs and what host they are currently on. The only thing is it only gives me the host ID not the name. Is there any way to get the name as well or lookup the name after it has got the id?
