How can PHP variables be appended to hidden fields for passing values in a form?

To append PHP variables to hidden fields for passing values in a form, you can simply echo the variable within the value attribute of the hidden input field. This way, when the form is submitted, the hidden field will contain the value of the PHP variable. 

<form action="process_form.php" method="post">
    <input type="hidden" name="hidden_field" value="<?php echo $variable; ?>">
    <!-- Other form fields here -->
    <input type="submit" value="Submit">
</form>
