How can the current scroll position be read in PHP to jump back to the same position after a refresh?

To read the current scroll position in PHP and jump back to the same position after a refresh, you can use JavaScript to store the scroll position in a cookie or session variable. Then, in your PHP code, you can retrieve the stored scroll position and use JavaScript to scroll back to that position after the page has been refreshed. 

<?php
session_start();

if(isset($_SESSION['scroll_position'])){
    echo '<script>window.scrollTo(0,' . $_SESSION['scroll_position'] . ');</script>';
}

if(isset($_POST['save_scroll_position'])){
    $_SESSION['scroll_position'] = $_POST['scroll_position'];
}

?>

    </form>
    
    <script>
        document.getElementById('scroll_position').value = window.scrollY;
    </script>
