On my fresh VPS managed by Webmin I have to use :

PHP functions : exec, shell_exec, posix_kill

PHP modules & options : zip, lib, soap, allow_url_fopen, allow_url_include, lib.output_compression

How to check what is already here and how to add the missing ones ?

Thanks.

I checked System -> Software Packages and Tools -> PHP Pear Modules but can’t find exactly what I look for.
