How can the EVA principle be applied to improve the structure of PHP functions in the given code snippet?

The EVA principle (Easier to Understand, Easier to Verify, Easier to Maintain) can be applied to improve the structure of PHP functions in the given code snippet by breaking down complex functions into smaller, more manageable functions with specific purposes. This will make the code easier to understand, verify, and maintain in the long run. 

// Original code snippet with complex function
function processUserData($data) {
    // Complex logic to process user data
    // ...
    return $processedData;
}

// Improved code snippet with smaller, more specific functions
function validateUserData($data) {
    // Validation logic for user data
    // ...
    return $isValid;
}

function sanitizeUserData($data) {
    // Sanitization logic for user data
    // ...
    return $sanitizedData;
}

function processUserData($data) {
    if (validateUserData($data)) {
        $sanitizedData = sanitizeUserData($data);
        // Process the sanitized data
        // ...
        return $processedData;
    } else {
        // Handle invalid user data
        // ...
        return false;
    }
}
