i am thinking about changing mysite domain with only ip address use to browse mysite so that i can use the domain for cheap package on other site btw since i have already paid for 1 year i want to just use ip address to browse mysite but my hosts says ip address doesnt support php files
Doesn't matter how you access the site: by FQDN domain name, or by IP. That is handled by DNS, which is a different server. The files served by the web server are ignorant of how they were addressed, and just serve. If you can do PHP now, you can do it later. Only things I can think of: 1) they're moving you to a different server, which does not have PHP installed 2) they use host headers to serve virtual domains, in which case you're domain itself can not be served by IP, regardless of it is PHP, PERL, JSP, HTML, etc... I'm leaning more towards number two being the case.
