What are some alternative solutions to the REGISTER GLOBALS issue in PHP?

The REGISTER GLOBALS issue in PHP refers to a configuration setting that allows variables to be automatically registered as global variables, which can lead to security vulnerabilities and unpredictable behavior. To solve this issue, one alternative solution is to use the $_GET, $_POST, and $_REQUEST superglobals to access form data instead of relying on register_globals.
