What is the significance of setting register_globals=off in the php.ini file?

Setting register_globals=off in the php.ini file is significant because it enhances security by preventing malicious users from easily manipulating variables in the global scope. When register_globals is on, user input can be directly assigned to variables, opening up the possibility of security vulnerabilities such as injection attacks. By turning it off, developers are encouraged to use superglobal arrays like $_GET, $_POST, and $_SESSION to access user input in a more controlled and secure manner.

// php.ini file
register_globals = Off;
