How can PHP beginners effectively troubleshoot issues related to data transmission between different form steps?

To effectively troubleshoot issues related to data transmission between different form steps in PHP, beginners can utilize session variables to store and retrieve data across multiple pages. By storing form data in session variables, it ensures that the data persists as the user navigates through different form steps. 

// Start the session
session_start();

// Store form data in session variables
$_SESSION['name'] = $_POST['name'];
$_SESSION['email'] = $_POST['email'];
$_SESSION['phone'] = $_POST['phone'];

// Retrieve form data from session variables
$name = $_SESSION['name'];
$email = $_SESSION['email'];
$phone = $_SESSION['phone'];
