How can PHP developers ensure that their scripts are clean and efficient when processing form data?

PHP developers can ensure that their scripts are clean and efficient when processing form data by properly sanitizing and validating input data to prevent security vulnerabilities and errors. They should also use efficient methods for processing the form data, such as using built-in PHP functions like filter_var() and htmlentities(). 

// Sanitize and validate input data
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);

// Process form data
if (!empty($name) && !empty($email)) {
    // Process the form data further
} else {
    // Handle invalid input data
}
