In PHP, what are some alternative methods to pass variables to the next page without exposing them in the URL or using sessions?

When passing variables between pages in PHP, using the URL or sessions can expose sensitive information. One alternative method is to use hidden form fields to pass variables between pages without displaying them in the URL or storing them in sessions. Another method is to encrypt the variables before passing them and decrypt them on the receiving page. 

// Sending page
<form method="post" action="next_page.php">
    <input type="hidden" name="variable_name" value="variable_value">
    <button type="submit">Submit</button>
</form>

// Receiving page
<?php
if(isset($_POST['variable_name'])){
    $variable = $_POST['variable_name'];
    // Use the variable as needed
}
?>
