What are the potential risks of enabling register_globals in PHP?

Enabling register_globals in PHP can pose security risks as it allows user input to automatically create global variables, making it easier for attackers to manipulate data and potentially execute malicious code. To mitigate this risk, it is recommended to disable register_globals in the PHP configuration settings.

// Disable register_globals in PHP configuration settings
// This can be done by setting the following line in php.ini file:
// register_globals = Off
