Add Pagination in page using PHP

How to create Pagination with PHP and MySql

<?php
if (isset($_GET['pageno'])) {
    $pageno = $_GET['pageno'];
} else {
    $pageno = 1;
}

$no_of_records_per_page = 10;
$offset = ($pageno-1) * $no_of_records_per_page;
$selectQuery = "SELECT id FROM tbl";
$resultselectCount = $db->query($selectQuery);

// count total rows
$total_rows = $resultselectCount->num_rows;

$query = "SELECT id FROM tbl LIMIT $offset, $no_of_records_per_page";
$selectdata = $db->query($query);

$total_pages = ceil($total_rows / $no_of_records_per_page);
if($pageno == '1'){
   $count = 1;
}else{
  $count = $pageno * 10 + 1 - 10;
}

while ($dataselectBanner = $selectdata->fetch_assoc()) {
  // your stuff goes here...
}

?>

// Your Source for pagination

<nav>
    <ul class="pagination">
      <li><a href="?pageno=1"><< First</a></li>
      <li class="<?php if($pageno <= 1){ echo 'disabled'; } ?>">
          <a href="<?php if($pageno <= 1){ echo '#'; } else { echo "?pageno=".($pageno - 1); } ?>">< Prev</a>
      </li>
      <li class="disabled"><a>Page <?php echo $pageno . " Of ". $total_rows/10;?></a></li>
      <li class="<?php if($pageno >= $total_pages){ echo 'disabled'; } ?>">
          <a href="<?php if($pageno >= $total_pages){ echo '#'; } else { echo "?pageno=".($pageno + 1); } ?>">Next ></a>
      </li>
      <li><a href="?pageno=<?php echo $total_pages; ?>">Last >></a></li>
  </ul>
</nav>
