How can variables be correctly set and referenced within heredoc syntax in PHP code for contact forms to ensure proper functionality?

When using heredoc syntax in PHP code for contact forms, variables can be correctly set and referenced by ensuring they are defined outside of the heredoc block and then referenced within it using the variable name. This helps ensure proper functionality of the contact form by allowing variables to be easily inserted into the text without causing syntax errors. 

<?php
// Define variables
$name = "John Doe";
$email = "johndoe@example.com";
$message = "Hello, how are you?";

// Use heredoc syntax to create the email body
$email_body = <<<EOD
Name: $name
Email: $email

$message
EOD;

// Additional code to send the email
?>
