Comment mettre en œuvre une pagination intelligente pour un contrôle amélioré de la pagination ?

<code class="php">// Limit the number of adjacent pages
$adjacents = 3;

// Fetch data for the current page
// ... (Code snippet omitted for brevity)

// Calculate pagination information
$total_pages = ceil($total_results / $limit);
$prev = $page - 1;
$next = $page + 1;
$lastpage = $lastpage - 1;

// Initialize pagination HTML markup
$pagination = '<nav aria-label="page navigation"><ul class="pagination">';

// Determine page range to display based on current page and adjacent page limit
if ($lastpage < 7 + ($adjacents * 2)) {
    // Display all pages
    for ($i = 1; $i <= $lastpage; $i++) {
        $pagination .= "<li class='page-item" . ($i == $page ? ' active' : '') . "'><a class='page-link' href='?page=$i'>$i</a></li>";
    }
} else {
    // Display first and last pages
    $pagination .= "<li class='page-item'><a class='page-link' href='?page=1'>1</a></li>";
    $pagination .= "<li class='page-item disabled'><span class='page-link'>...</span></li>";
    $pagination .= "<li class='page-item'><a class='page-link' href='?page=$lastpage'>$lastpage</a></li>";

    // Display pages adjacent to the current page
    if ($page < 1 + ($adjacents * 2)) {
        // Display pages near the beginning
        for ($i = 1; $i < 4 + ($adjacents * 2); $i++) {
            $pagination .= "<li class='page-item" . ($i == $page ? ' active' : '') . "'><a class='page-link' href='?page=$i'>$i</a></li>";
        }
    } elseif ($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2)) {
        // Display pages in the middle
        $pagination .= "<li class='page-item disabled'><span class='page-link'>...</span></li>";
        for ($i = $page - $adjacents; $i <= $page + $adjacents; $i++) {
            $pagination .= "<li class='page-item" . ($i == $page ? ' active' : '') . "'><a class='page-link' href='?page=$i'>$i</a></li>";
        }
    } else {
        // Display pages near the end
        $pagination .= "<li class='page-item disabled'><span class='page-link'>...</span></li>";
        for ($i = $lastpage - (2 + ($adjacents * 2)); $i <= $lastpage; $i++) {
            $pagination .= "<li class='page-item" . ($i == $page ? ' active' : '') . "'><a class='page-link' href='?page=$i'>$i</a></li>";
        }
    }
}

// Display previous and next page links
if ($page != 1) {
    $pagination .= "<li class='page-item'><a class='page-link' href='?page=$prev'>Previous</a></li>";
}
if ($page != $lastpage) {
    $pagination .= "<li class='page-item'><a class='page-link' href='?page=$next'>Next</a></li>";
}

// Output pagination HTML
echo $pagination . '</ul></nav>';</code>
