這篇文章主要介紹了zf框架db類的分頁(yè)示例,代碼很簡(jiǎn)單，大家看一下注釋就可以使用了

zf框架的分頁(yè)示例

代碼如下:

<?php

isset($_GET['page']) ? $page = $_GET['page'] : $page = 1;

//引入Loader類(自動(dòng)加載類)

require_once("Zend/Loader.php");

//使用Loader類引入一個(gè)Db類

Zend_Loader::loadClass("Zend_Db");

//引入Zend_Db的狀態(tài)器

Zend_Loader::loadClass("Zend_Db_Statement_Pdo");

//配置數(shù)據(jù)庫(kù)連接信息

$Config = array('host' => '127.0.0.1' ,

'username' => 'root' ,

'password' => '111' ,

'dbname' => 'test',

'profiler' => "true"

);

//告訴Zend_Db類所操作的數(shù)據(jù)庫(kù)和數(shù)據(jù)庫(kù)配置信息

$Db = Zend_Db::factory('PDO_Mysql' , $Config);

//執(zhí)行編碼語(yǔ)句

$Db -> query("set names utf8");

//-----------------------------------------------

//使用fetchOne()方法得出表的總條數(shù)

$Total = $Db -> fetchOne("select count(*) from gongsi");

//定義每頁(yè)顯示條數(shù)

$B = 50;

//得出總頁(yè)數(shù)

$A = ceil($Total/$B);

//-----接下來為一系列的查詢表、取結(jié)果集、分頁(yè)等操作

$Select = $Db ->select();

$Select -> from('sanguo',array('s_sheng as 省份','sum(s_gongzi) as 總工資','min(s_gongzi) as 最低工資','max(s_gongzi) as 最高工資','avg(s_gongzi) as 平均工資'));

// $Select -> Where('s_gongzi>=3000');

// $Select -> Where("s_sheng='河北'");

// $Select -> order('s_sheng asc');

// $Select -> order('s_gongzi desc');

$Select -> group('s_sheng'); //分組

//$Select -> having('最高工資>10000'); //附加條件

$Select -> order('最高工資 desc'); //排序

$Select -> limit(0,0); //截取

$Select -> limitPage($page, $B); //分頁(yè)

/*SQL語(yǔ)句相當(dāng)于：

select s_sheng as 省份,sum(s_gongzi) as 最高工資 from sanguo group by s_sheng having 最高工資>10000 order by 最高工資 desc limit 0,10;

*/

$Result = $Db->fetchAll($Select);

echo "<table border='1' align='center' width='960' style='text-align:center'>";

echo "<tr><th>省份</th><th>總工資</th><th>最低工資</th><th>最高工資</th><th>平均工資</th></tr>";

foreach ($Result as $key => $value)

{

echo "<tr>";

foreach ($value as $key2 => $value2)

{

echo "<td>" . $value2 . "</td>";

}

echo "</tr>";

}

echo "<tr>";

echo "<td colspan='5'>";

echo "<a href=?page=1>首頁(yè)</a> ";

if ($page>1)

{

echo "<a href=?page=". ($page-1) .">上頁(yè)</a> ";

}

for ($i=1; $i <=15 ; $i++)

{

echo "<a href=?page=$i>".$i."</a> ";

}

if ($page<$Total)

{

echo "<a href=?page=". ($page+1) .">下頁(yè)</a> ";

}

echo "<a href=?page=" . $A .">末頁(yè)</a>";

echo "</td>";

echo "</tr>";

echo "</table>";

?>
