php利用msqli访问数据库并实现分页，

<?php 
require_once 'login.php';
$num_rec_per_page=2;   // 每页显示数量
//mysql_connect('localhost','jim','0000');  // 数据库连接
//mysql_select_db('publications');  // 数据库名
    $conn = new mysqli($db_hostname, $db_username, $db_password, $db_database);
if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; }; 
$start_from = ($page-1) * $num_rec_per_page; 
$query = "SELECT * FROM user LIMIT $start_from, $num_rec_per_page"; 
//$rs_result = mysql_query ($sql); // 查询数据
$result = $conn->query($query);
?> 
<table>
<tr><td>Name</td><td>Phone</td></tr>
<?php 
//while ($row = mysql_fetch_assoc($result)) {
while ($row = $result->fetch_array(MYSQLI_NUM)) { 

?> 
            <tr>
            <td><?php echo $row[0]; ?></td>
            <td><?php echo $row[1]; ?></td>            
            </tr>
<?php 
}; 
?> 
</table>
<?php 
$sql = "SELECT * FROM user"; 
$result = $conn->query($sql); //查询数据
$total_records = mysqli_num_rows($result);  // 统计总共的记录条数
$total_pages = ceil($total_records / $num_rec_per_page);  // 计算总页数

echo "<a href='fenyetest.php?page=1'>".'|<'."</a> "; // 第一页

for ($i=1; $i<=$total_pages; $i++) { 
            echo "<a href='fenyetest.php?page=".$i."'>".$i."</a> "; 
}; 
echo "<a href='fenyetest.php?page=$total_pages'>".'>|'."</a> "; // 最后一页，注意把网址改到当前页
?>

注意mysql与mysqli的不同
