What are some recommended approaches for structuring and processing form data for different inputs in PHP?

When working with form data in PHP, it's important to properly structure and process the inputs to ensure security and accuracy. One recommended approach is to use the $_POST superglobal to retrieve form data submitted via POST method. You can then sanitize and validate the data using functions like filter_var() or htmlspecialchars() before further processing. 

// Retrieve form data submitted via POST method
$name = isset($_POST['name']) ? $_POST['name'] : '';
$email = isset($_POST['email']) ? $_POST['email'] : '';

// Sanitize and validate the data
$name = filter_var($name, FILTER_SANITIZE_STRING);
$email = filter_var($email, FILTER_VALIDATE_EMAIL);

// Further processing of the form data
// (e.g. saving to a database, sending an email, etc.)
