How can PHP beginners improve their code formatting and organization to prevent confusion and errors in form handling?

To improve code formatting and organization in PHP for form handling, beginners can utilize proper indentation, consistent naming conventions, and comments to explain the purpose of each section of code. By structuring their code logically and consistently, beginners can prevent confusion and errors when working with form data. 

<?php

// Handle form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Sanitize input data
    $name = htmlspecialchars($_POST["name"]);
    $email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
    $message = htmlspecialchars($_POST["message"]);
    
    // Validate input data
    if (empty($name) || empty($email) || empty($message)) {
        echo "Please fill out all fields.";
    } else {
        // Process form data
        // Code to handle form data goes here
    }
}

?>
