这篇文章主要介绍了zf框架db类的分页示例,代码很简单，大家看一下注释就可以使用了

zf框架的分页示例

代码如下:

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

//引入Loader类(自动加载类)

require_once("Zend/Loader.php");

//使用Loader类引入一个Db类

Zend_Loader::loadClass("Zend_Db");

//引入Zend_Db的状态器

Zend_Loader::loadClass("Zend_Db_Statement_Pdo");

//配置数据库连接信息

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

'username' => 'root' ,

'password' => '111' ,

'dbname' => 'test',

'profiler' => "true"

);

//告诉Zend_Db类所操作的数据库和数据库配置信息

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

//执行编码语句

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

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

//使用fetchOne()方法得出表的总条数

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

//定义每页显示条数

$B = 50;

//得出总页数

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

//-----接下来为一系列的查询表、取结果集、分页等操作

$Select = $Db ->select();

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

// $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'); //分组

//$Select -> having('最高工资>10000'); //附加条件

$Select -> order('最高工资 desc'); //排序

$Select -> limit(0,0); //截取

$Select -> limitPage($page, $B); //分页

/*SQL语句相当于：

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

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

echo "";
echo "
";
foreach ($Result as $key => $value)
{
echo "
";
foreach ($value as $key2 => $value2)
{
echo "
";
}
echo "
";
}
echo "
";
echo "
";
echo "
";
echo "

省份总工资最低工资最高工资平均工资

" . $value2 . "

";

echo "首页 ";

if ($page>1)

{

echo "上页 ";

}

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

{

echo "".$i." ";

}

if ($page<$Total)

{

echo "下页 ";

}

echo "末页";

echo "

";

省份	总工资	最低工资	最高工资	平均工资
" . $value2 . "
"; echo "首页 "; if ($page>1) { echo "上页 "; } for ($i=1; $i <=15 ; $i++) { echo "".$i." "; } if ($page<$Total) { echo "下页 "; } echo "末页"; echo "
