zf框架的db类select查询器join链表使用示例(zend框架)

<?php
//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");
//-----------------------------------------------
$select = $db ->select();
$select -> from('sanguo','*');
$select -> join('dengji','sanguo.s_dengji = dengji.d_id');
$select -> order('s_dengji asc');
$reslut = $db -> fetchall($select);
echo "<table border='1' width='600' style='text-align:center'>";
foreach ($reslut as $key => $value)
{
 echo "<tr>";
 foreach ($value as $key2 => $value2)
 {
  echo "<td>" . $value2 . "</td>";
 }
 echo "</tr>";
}
echo "</table>";
