suppose i'm developing a web app in which I need to show the remaining disk space on the server to the user. So I use the 'disk_free_space' php function to get that info. Now this is gonna work on my local machine( the one i'm developing on ) and it's gonna work on a dedicated server( which is the same as my own local machine ). I don't know if it would work on a vps and I know that it WOULDN'T work on a shared server. ( by working I mean showing the correct amount ). So my question is, that if i develop my app on my local machine, which acts like a dedicated server, would I have such problems if I deployed the script on a VPS?
Thanks
