How does the configuration of register_globals impact the passing of variables in PHP scripts?

When register_globals is enabled in PHP, it automatically creates global variables from user input, which can lead to security vulnerabilities such as injection attacks. It is recommended to disable register_globals in PHP configuration settings to prevent these risks. To pass variables securely in PHP scripts without relying on register_globals, you can use superglobal arrays like $_GET, $_POST, or $_REQUEST to access form data or query parameters. 

// Disable register_globals in PHP configuration settings

// Accessing variables securely using superglobal arrays
$variable_name = $_POST['variable_name'];
