ZF框架Db类select查询器join链表简单用法

<?php
/*查询器的join()链表使用方法*/

//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(&#39;host&#39; => &#39;127.0.0.1&#39; ,
				&#39;username&#39; => &#39;root&#39; , 
				&#39;password&#39; => &#39;111&#39; , 
				&#39;dbname&#39; => &#39;test&#39;,
				&#39;profiler&#39; => "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(&#39;PDO_Mysql&#39; , $Config); 
//执行编码语句 
$Db -> query("set names utf8");
//-----------------------------------------------
$Select = $Db ->select();
$Select -> from(&#39;sanguo&#39;,&#39;*&#39;);
$Select -> join(&#39;dengji&#39;,&#39;sanguo.s_dengji = dengji.d_id&#39;);
$Select -> order(&#39;s_dengji asc&#39;);
$Reslut = $Db -> fetchAll($Select);
echo "<table border=&#39;1&#39; width=&#39;600&#39; style=&#39;text-align:center&#39;>";
foreach ($Reslut as $key => $value) 
{
	echo "<tr>";
	foreach ($value as $key2 => $value2) 
	{
		echo "<td>" . $value2 . "</td>";
	}
	echo "</tr>";
