The PHP safe mode is an attempt to solve the shared environment server security problem. It is architecturally incorrect to try and solve this problem at the PHP level.
Limit the files that can be opened by PHP to the specified directory-tree, including the file itself. This directive is NOT affected by whether Safe Mode is turned On or Off.
Note: Due to the security purpose, safe_mode and open_basedir are activated in Exabytes Shared Environment server.
