PHP MySql paging example
The following example demonstrates PHP querying data through the Mysql database and performing paging:
<?php
$num_rec_per_page=10; // 每页显示数量
mysql_connect('localhost','root',''); // 数据库连接
mysql_select_db('apex1'); // 数据库名
if (isset($_GET["page"])) {
$page = $_GET["page"]; }
else { $page=1; };
$start_from = ($page-1) * $num_rec_per_page;
$sql = "SELECT * FROM student LIMIT $start_from, $num_rec_per_page";
$rs_result = mysql_query ($sql); // 查询数据?>
<table><tr><td>Name</td><td>Phone</td></tr><?php
while ($row = mysql_fetch_assoc($rs_result)) { ?>
<tr>
<td><?php echo $row['Name']; ?></td>
<td><?php echo $row['Phone']; ?></td>
</tr><?php
}; ?> </table><?php
$sql = "SELECT * FROM student"; $rs_result = mysql_query($sql); //查询数据
$total_records = mysql_num_rows($rs_result); // 统计总共的记录条数
$total_pages = ceil($total_records / $num_rec_per_page); // 计算总页数
echo "<a href='pagination.php?page=1'>".'|<'."</a> "; // 第一页
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination.php?page=".$i."'>".$i."</a> "; };
echo "<a href='pagination.php?page=$total_pages'>".'>|'."</a> "; // 最后一页?>This article introduces PHP MySql paging examples. For more related knowledge, please pay attention to the php Chinese website.
