How can special characters like quotes be properly handled in hidden input fields in PHP to prevent data loss?

Special characters like quotes can be properly handled in hidden input fields in PHP by using the htmlspecialchars function to encode the special characters before placing them in the input field. This prevents any data loss or unwanted behavior when the form is submitted. 

<?php
// Get the value from a form input field
$value = $_POST['input_field'];

// Encode the special characters before placing them in a hidden input field
echo '<input type="hidden" name="hidden_field" value="' . htmlspecialchars($value) . '">';
?>
