How does the register_globals setting impact the availability of variables in included PHP scripts?

When the register_globals setting is enabled in PHP, it automatically creates global variables for any incoming request parameters. This can lead to security vulnerabilities and make it difficult to track the source of variables in included scripts. To solve this issue, it is recommended to disable the register_globals setting in the php.ini configuration file.

// Disable register_globals in php.ini
// Add the following line to php.ini file
// register_globals = Off
