Migration to group server PHP concerns

Hello,

My web host server (pairNetworks) is suggesting I move from the legacy servers to the new group servers.

Among others they caution the following, which I know nothing about except my email forms (generally in FormLoom of one flavour or another) use PHP.

Does anyone know offhand if this would concern me, or how I would find that out?

PHP’s register_globals is turned off by default

You are using one or more .php scripts. Not all php scripts will run

without modification on a server group web server. Specifically, any

script that requires the register_globals setting to be turned on will

fail, because this is turned off on group web servers.
