How can PHP and HTML work together to create a seamless user experience when dealing with checkbox selection limits?

When dealing with checkbox selection limits, PHP can be used to handle the logic of limiting the number of checkboxes that can be selected. This can be achieved by checking the number of checkboxes that have been selected and preventing any additional checkboxes from being selected once the limit has been reached. By integrating this logic with HTML, users will have a seamless experience where they are notified when they reach the selection limit. 

<?php
$limit = 3; // Set the limit for checkbox selection
$selectedCount = count($_POST['checkbox']); // Get the number of checkboxes selected

if($selectedCount > $limit) {
    echo "You can only select up to $limit checkboxes.";
} else {
    // Process the selected checkboxes
}
?>
