Hi list!

I'm no php developer, just a few ideas really.

Would it be possible to disable all unused functions per
group, that are compiled into php4, using directives in
php.ini?

Could be ideal for testing purposes, and for others that
want to use different configurations of the same php_module,
without having to keep compiling different flavoured versions.

Should also help in tightening up security issues too.

Something like:

php.ini

...

Disable_XYZ On|Off

Which would disable ALL functions for that particular

group, such as:

Disable_Filesystem On|Off

would disable all the functions in the filesystem group

Disable_Directory On|Off

would disable all functions in the directory group

Then to selectively allow the ENABLING of required

functions from a particular group, use something like:

Enable_Filesystem_functions move_uploaded_file, rename

which would allow use of the above 2 functions from the

filesystem group, but still leaving the others disabled.

...

Obviously, there must be a number of core functions that
php needs, and these probably cannot be disabled.

Would this be practical?
