Add new PHP modules

Little confused about adding modules to PHP using the edit flags.

I see:

--enable-zip
--with-gd

Since these are both modules, what is the difference between --enable and --with?

I need to add modules to PHP7 (and 5.6) but before doing so like to learn proper way.

These seem to be available modules and very confused at proper way to use --enable and --with. Sure I feel stupid when explained but feel better knowing:) When updating to PRO was just told to enable...

Code: [Select]

well you can always use google and save 7$, for sysvmsg module type in google :  php comile sysvmsg . I got this page : http://php.net/manual/en/sem.installation.php

Thanks @frprim. Yea pretty good at using google before asking questions but in this case did not find info needed.

I guess me just stupid because cannot grasp any of the info using link you googled.

Thanks anyway for at least trying to help.
