I am trying to install Drupal on a virtual dedicated server (vps). I am installing php 4.
It asks if I want to enable the following six php functions:
cmd
passthru
popen
proc_open
shell_exec
system.
Enabling them is a security risk, but some things won't work without them.
I looked in the handbook on the server requirements page and didn't see any answers.

I searched and found this:
filestore2 might require passthru
imagemagick might require popen
installation of Drupal might require proc_open
massmailer and acidfree seems to require shell_exec
I didn't try searching on system and cmd, thinking there would be too many other terms.
Can someone tell me whether I need to enable all six?
