How can PHP functions be effectively used to streamline the process of handling form data for multiple purposes?

When handling form data for multiple purposes, PHP functions can be effectively used to streamline the process by creating reusable functions that validate, sanitize, and process the data. By encapsulating these tasks within functions, you can easily call them whenever needed without duplicating code. 

// Function to validate form data
function validateFormData($data) {
    // Add your validation logic here
    return $validatedData;
}

// Function to sanitize form data
function sanitizeFormData($data) {
    // Add your sanitization logic here
    return $sanitizedData;
}

// Function to process form data
function processFormData($data) {
    // Add your processing logic here
    return $processedData;
}

// Example of using the functions
$rawFormData = $_POST['form_data'];
$validatedData = validateFormData($rawFormData);
$sanitizedData = sanitizeFormData($validatedData);
$processedData = processFormData($sanitizedData);
