How does using hidden fields with GET or POST compare to other methods for saving user-selected values in PHP applications?

Using hidden fields with GET or POST allows developers to save user-selected values in PHP applications by passing the values between pages without displaying them to the user. This method is commonly used for passing data from one page to another without the need for a database or session storage. It is a simple and effective way to preserve user selections throughout a user's session on a website. 

// Example of using hidden fields with POST to save user-selected values

<form method="post" action="next_page.php">
    <input type="hidden" name="selected_value" value="example_value">
    <button type="submit">Submit</button>
</form>

// next_page.php
<?php
$selected_value = $_POST['selected_value'];
echo "User selected value: " . $selected_value;
?>
