What is the best practice for transferring data from one form to another in PHP?

When transferring data from one form to another in PHP, the best practice is to use POST method to securely send the data from the first form to the server, and then retrieve and display the data in the second form using PHP. This ensures that the data is not visible in the URL and is transmitted securely. 

// First form that sends data using POST method
<form action="second_form.php" method="post">
    <input type="text" name="data_to_transfer">
    <button type="submit">Submit</button>
</form>

// Second form that receives and displays the transferred data
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $transferred_data = $_POST['data_to_transfer'];
    echo "Transferred Data: " . $transferred_data;
}
?>
