Are there any alternative approaches or technologies that can be used in conjunction with PHP to maintain scroll position after a page refresh?
When a page is refreshed in PHP, the scroll position is typically reset to the top of the page. To maintain the scroll position after a page refresh, you can use JavaScript in conjunction with PHP to store the current scroll position in a session variable before the page is refreshed, and then set the scroll position back to the stored value after the page is reloaded.
<?php
session_start();
if(isset($_POST['scroll_position'])){
$_SESSION['scroll_position'] = $_POST['scroll_position'];
}
$scroll_position = isset($_SESSION['scroll_position']) ? $_SESSION['scroll_position'] : 0;
?>

<script>
document.addEventListener("DOMContentLoaded", function(){
document.getElementById('scrollPosition').value = window.scrollY;
document.getElementById('scrollForm').submit();
});
window.onload = function(){
window.scrollTo(0, <?php echo $scroll_position; ?>);
};
