How can PHP developers handle form submissions when register_globals is turned off?

When register_globals is turned off, PHP developers can handle form submissions by accessing form data through superglobal arrays like $_POST, $_GET, or $_REQUEST. This ensures that data is not automatically imported into the global scope, improving security and preventing potential vulnerabilities. 

// Example code snippet to handle form submission when register_globals is turned off
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // Process form data or perform validation
}
