What is PHP Safe Mode?

PHP safe mode is a security feature that was designed to prevent hackers from being able to use PHP scripts to execute commands at the operating system level (such as Linux shell commands).

It was intended to be a security method for web applications running on shared hosting accounts, as VPS and dedicated servers running single web hosting accounts did not need it. It never functioned well, however, and PHP developers have removed it from the upcoming version 6 release.
