实现效果

准备工作

创建数据表和导入测试数据

CREATE TABLE `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(30) DEFAULT NULL COMMENT '账号',
`email` varchar(30) DEFAULT NULL COMMENT '密码',
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

INSERT INTO `users` VALUES ('1', 'admin', 'admin@qq.com');

INSERT INTO `users` VALUES ('2', 'xiaoming', '123456@qq.com');

INSERT INTO `users` VALUES ('3', 'xiaoming1', '123456@qq.com');

INSERT INTO `users` VALUES ('4', 'xiaoming2', '123456@qq.com');

INSERT INTO `users` VALUES ('5', 'xiaoming3', '123456@wy.com');

INSERT INTO `users` VALUES ('6', 'xiaoming4', '123456@wy.com');

INSERT INTO `users` VALUES ('7', 'xiaoming5', '123456@wy.com');

INSERT INTO `users` VALUES ('8', 'xiaoming6', '123456@wy.com');

INSERT INTO `users` VALUES ('9', 'xiaoming7', '123456@wy.com');

一、php实现分页功能一（跳转方式）

一、php实现分页功能一（跳转方式）

<?php
// 连接数据库
$conn = new mysqli('localhost', 'root', 'root', 'aaa');
// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败：" . $conn->connect_error);
}
// 每页显示的记录数
$records_per_page = 3;
// 获取当前页数，默认为第一页
if (isset($_GET['page']) && is_numeric($_GET['page'])) {
    $current_page = $_GET['page'];
} else {
    $current_page = 1;
}
// 计算总记录数
$query = "SELECT COUNT(*) AS total_records FROM users";
$result = $conn->query($query);
$row = $result->fetch_assoc();
$total_records = $row['total_records'];
// 计算总页数
$total_pages = ceil($total_records / $records_per_page);
// 计算偏移量
$offset = ($current_page - 1) * $records_per_page;
// 查询数据
$query = "SELECT * FROM users LIMIT $offset, $records_per_page";
$result = $conn->query($query);
?>

<h1>用户列表</h1>
<table>
    <tr>

    </tr>
    <?php while ($row = $result->fetch_assoc()): ?>
        <tr>
            <td><?php echo $row['id']; ?></td>

<div>
    <?php if ($current_page > 1): ?>
        <a href="?page=1">首页</a>
        <a href="?page=<?php echo $current_page - 1; ?>">上一页</a>
    <?php endif; ?>

    当前页：<?php echo $current_page; ?> / <?php echo $total_pages; ?>

    <?php if ($current_page < $total_pages): ?>
        <a href="?page=<?php echo $current_page + 1; ?>">下一页</a>

if (isset($_GET['page']) && is_numeric($_GET['page'])) {
    $current_page = $_GET['page'];
} else {
    $current_page = 1;
}
// 计算总记录数
$query = "SELECT COUNT(*) AS total_records FROM users";
$result = $conn->query($query);
$row = $result->fetch_assoc();
$total_records = $row['total_records'];
// 计算总页数
$total_pages = ceil($total_records / $records_per_page);
// 计算偏移量
$offset = ($current_page - 1) * $records_per_page;
// 查询数据
$query = "SELECT * FROM users LIMIT $offset, $records_per_page";
$result = $conn->query($query);
// 构建返回的JSON数据
$data = array();
while ($row = $result->fetch_assoc()) {
    $data[] = $row;
}
$response = array(
    'data' => $data,
    'current_page' =>(int) $current_page,
    'total_pages' => $total_pages
);
echo json_encode($response);
