                    $total_pages = ceil($total_records / $limit);  
                    $pagLink = "<div class='container'><ul class='pagination'>";  
                    for ($i=1; $i<=$total_pages; $i++) {  
                    $pagLink .= "<li><a href='medicines.php?page=".$i."'>".$i."</a></li>";
