我正在尝试创建一个显示数据库中缩略图的页面。但是，如果我想更新数据库，我想创建一个分页。只有前3个表应在第1页中显示，依此类推...
这是我在缩略图中的脚本
<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost", "root", "", "test");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Attempt select query execution
$sql = "SELECT * FROM news limit 3";
if($result = mysqli_query($link, $sql)){
if( mysqli_num_rows($result) > 0 ){
echo "<div class="container">";
echo "<table>";
echo "<tr>";
echo "</tr>";
while($row=mysqli_fetch_array($result)){
echo "<div class="col-md-4">";
echo "<div class="thumbnail">";
echo "<img alt="News" src="images/{$row["image"]}">";
echo "<div class="caption">";
echo "<b><h4>{$row["title"]}</b></h4>";
echo "<p>{$row["caption"]}</p>";
echo "<p align="right">";
echo "<a class="btn btn-primary" href="{$row["newsupdate"]}">Read More</a>";
echo "</p>";
echo "</div>";
echo "</div>";
echo "</div>";
echo "</div>";
}
echo "</table>";
// Free result set
mysqli_free_result($result);
} else{
echo "No records matching your query were found.";
}
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
// Close connection
mysqli_close($link);
?>
<ul class="pagination">
<li><a href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
<li><a href="#">5</a></li>
</ul>
您是否要嘲笑出现的表格？
我认为使用Bootstrap或jQuery的分页是一个不错的选择：

您可以配置每页显示的项目，样式等。
为了通过您的记录集划分，将显示器限制为一次指定数量的记录，您需要更改SQL查询以使用offset和total值的limit值条款。通常，分页使用获取变量来确定用户当前打开的页面，并且此变量在SQL查询中使用。
以下是我刚刚通过特定的记录集写的基本示例 - 使用代码并更改您的特定查询应该很简单。
<?php
$dbhost = 'localhost';
$dbuser = 'xxx';
$dbpwd = 'xxx';
$dbname = 'xxx';
$db = new mysqli( $dbhost, $dbuser, $dbpwd, $dbname );
?>

#paging *{margin:0.5rem 1rem;clear:none!important;display:inline-block;}
.minimal{margin:0.5rem 0.1rem!important;}
</style>

$page = isset( $_GET['page'] ) ? filter_input( INPUT_GET, 'page', FILTER_SANITIZE_NUMBER_INT ) : 0;
if( is_numeric( $page ) && $page >= 0 ){
$rpp = 10; /* Records Per Page */
$offset = $page * $rpp; /* paging offset */
/*
In order to determine the paging you need to know the total number of records available
that are returned by the query with any given WHERE clause. The sub-query therefore uses
the same WHERE clause and returns a number to be used later.
Edit the sql to suit your needs and edit the data that is rendered in the while loop.
