你应该知道的PHP+MySQL分页那点事

Mysql Fixed Assets Table"; echo "// 循环显示总页数
?>
<?php
echo '<a href="SlicePage.php?page_number=1">首页';
for($i=1;$i<=$total_pages;$i++){
echo '<a href="./SlicePage.php?page_number='.$i.'">第'.$i.'页';
}
echo '<a href="SlicePage.php?page_number='.($current_page_number-1).'">上一页';
echo '<a href="SlicePage.php?page_number='.($current_page_number+1).'">下一页';
echo '<a href="SlicePage.php?page_number='.($total_pages).'">尾页';

分页实现

了解了上面的内容之后，下面来看一下这个完整的例子吧。

代码SlicePage.PHP

rush:PHP;"> <Meta charset="utf-8"> PHP //解决中文乱码,发现不能奏效，则考虑MysqL客户端乱码情况 header("Content-type=text/html;charset=utf-8");

$host = "localhost";
$username = "root";
$password = "MysqL";
$dbname = "MysqL";

// 开始获取数据库连接
$conn = MysqL_connect($host,$username,$password) or die(MysqL_error());
// 手动更改客户端编码
MysqL_query("set names utf8");
// 选择使用哪一个数据库
 MysqL_select_db($dbname);

// 获取总的记录数
$sql_total_records = "select count(*) from innodb_table_stats";
$total_records_result = MysqL_query($sql_total_records);
$total_records = MysqL_fetch_row($total_records_result);
echo "总的记录数位： ".$total_records[0]."
";

// 获得总页数，一般来说页面大小事固定的，所以这里暂且定为一页5个数据
$page_size = 3;
$total_pages = ceil($total_records[0]/$page_size);
echo "总页数为: ".$total_pages;

// 通过GET方式获得客户端访问的页码
$current_page_number = isset($_GET['page_number'])?$_GET['page_number']:1;
if($current_page_number<1) {
$current_page_number =1;
}
if($current_page_number>$total_pages){
$current_page_number = $total_pages;
}
echo "要访问的页码为：".$current_page_number;

// 获取到了要访问的页面以及页面大小，下面开始分页
$begin_position = ($current_page_number-1)$page_size;
$sql = "select from innodb_table_stats limit $begin_position,$page_size";
$result = MysqL_query($sql);

// 处理结果集
echo "

";
echo "<tr><td>dbname</td><td>TableName</td><td>Lastupdate</td><td>nNows</td><td>Clustered_Index_Size</td><td>Sum_od_Other_Index_sizes</td></tr>";
while(($row = MysqL_fetch_row($result))){
echo "<tr>";
echo "<td>".$row[0]."</td>";
echo "<td>".$row[1]."</td>";
echo "<td>".$row[2]."</td>";
echo "<td>".$row[3]."</td>";
echo "<td>".$row[4]."</td>";
echo "<td>".$row[5]."</td>";
echo "</tr>";
}
echo "</table>";

// 循环显示总页数
?>
<?PHP
echo '<a href="SlicePage.PHP?page_number=1">首页';
for($i=1;$i<=$total_pages;$i++){
echo '<a href="./SlicePage.php?page_number='.$i.'">第'.$i.'页';
}
echo '<a href="SlicePage.php?page_number='.($current_page_number-1).'">上一页';
echo '<a href="SlicePage.php?page_number='.($current_page_number+1).'">下一页';
echo '<a href="SlicePage.php?page_number='.($total_pages).'">尾页';
// 释放数据连接资源
mysql_free_result($result);
mysql_close($conn);
