PHP finally removed safe_mode feature:
This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.
The PHP safe mode is an attempt to solve the shared-server security problem. It is architecturally incorrect to try to solve this problem at the PHP level, but since the alternatives at the web server and OS levels aren't very realistic, many people, especially ISP's, use safe mode for now.
My question is:
What are possible consequences for applications that depends on Safe Mode for security?
