What are best practices for structuring and organizing HTML and PHP code in registration scripts to improve readability and maintainability?

To improve readability and maintainability in registration scripts, it is recommended to separate HTML and PHP code by using a templating system like PHP's alternative syntax or a front-end framework like Bootstrap. Additionally, organizing code into functions for specific tasks such as validating input, processing form data, and displaying messages can make the code easier to follow. Lastly, commenting code thoroughly and consistently following naming conventions can also enhance readability and maintainability. 

<?php
// Validate input
function validateInput($data) {
    // Validation logic here
}

// Process form data
function processFormData($data) {
    // Processing logic here
}

// Display success message
function displaySuccessMessage() {
    // Success message display logic here
}

// Display error message
function displayErrorMessage($error) {
    // Error message display logic here
}

// Main registration script
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $formData = $_POST;

    // Validate input
    if (validateInput($formData)) {
        // Process form data
        processFormData($formData);
        displaySuccessMessage();
    } else {
        displayErrorMessage("Invalid input. Please try again.");
    }
}
?>
