Security issue with php.ini

Hello,

In our deployment (cbpolis.com), we will not allow each user to edit its own php.ini, and we would like to limit for each user the access right of the php scripts.

In order to do this, we use the open_basedir directive of php.ini.

We would like to be able to update in one shot all php.ini files in every user's folder.

Is it possible to add a function which allow global edit and modification ?

Thank you, Guy.
