Are there specific tutorials or resources available to help with implementing a reload lock in PHP?

To implement a reload lock in PHP, you can use session variables to keep track of whether a page has already been loaded. By setting a session variable when a page is loaded and checking for its existence before loading the page again, you can prevent unwanted page reloads. 

session_start();

if(!isset($_SESSION['page_loaded'])) {
    // Page content goes here

    $_SESSION['page_loaded'] = true;
}
