The key differences between simple, extended, and extreme extended "Seiten-blättern-Scripts" lie in their functionality and complexity. Simple scripts typically provide basic pagination features such as next and previous buttons. Extended scripts may include additional features like page number navigation or customizable page sizes. Extreme extended scripts could have advanced functionalities like AJAX loading, dynamic content updates, or multiple sorting options.

function simple_pagination($total_pages, $current_page) {
    // Display next and previous buttons
}

}

// Extreme extended pagination script
function extreme_extended_pagination($total_pages, $current_page) {
    // Include AJAX loading, dynamic content updates, multiple sorting options, etc.
