Allow access to /proc/self for processes that get started from PHP

to run an application who allow to sign pdf online i need to allow access to “/proc/self” for processes that get started from PHP.

How to do that from plesk + ubuntu ? Is a safe option for the vps ?

I think that the command should be

mount –bind /proc /var/www/vhosts/…/websitepath

But i don’t really know if it’s a good move or nope :/ any help?
