PHP scripts run on the server, so if you request a PHP script from
another server, it will run on the remote. You will get only the output
from that script, just as if you were to request it from a browser.

But rather than set variables before including the script, check out
functions and passing parameters to them. It makes your code much more
maintainable and reliable.
