What are the best practices for handling global variables like register_globals in PHP scripts?

The best practice for handling global variables like register_globals in PHP scripts is to disable this feature for security reasons. This can be done by setting the value of the register_globals directive to "Off" in the php.ini configuration file. Additionally, developers should use superglobal arrays like $_GET, $_POST, and $_SESSION to access external input data instead of relying on global variables.

// Disable register_globals in php.ini
// Set the value to "Off"
// php.ini file
// register_globals = Off
