In what scenarios is it advisable to reload a page and pass parameters via GET requests for handling user actions in PHP?

When you need to handle user actions that require passing parameters between pages, it is advisable to reload the page and pass parameters via GET requests in PHP. This allows you to maintain the state of the application and perform actions based on the parameters passed in the URL. 

<?php
// Check if a parameter is passed in the URL
if(isset($_GET['action'])) {
    // Perform actions based on the parameter value
    $action = $_GET['action'];
    
    switch($action) {
        case 'delete':
            // Delete functionality
            break;
        case 'update':
            // Update functionality
            break;
        default:
            // Default action
            break;
    }
}

// Reload the page with parameters
echo '<a href="page.php?action=delete">Delete</a>';
echo '<a href="page.php?action=update">Update</a>';
?>
