How can PHP developers ensure their scripts are not reliant on register_globals being set to on?

When register_globals is set to on, it allows PHP scripts to access global variables based on the name of form inputs or query parameters. This can lead to security vulnerabilities and make the code harder to maintain. To ensure scripts are not reliant on register_globals being on, developers should use superglobal arrays like $_POST, $_GET, and $_REQUEST to access form input and query parameters. 

// Instead of relying on register_globals, use superglobal arrays to access form input and query parameters
$username = $_POST['username'];
$password = $_POST['password'];

// Example of processing form data securely without relying on register_globals
