加载数据的页面jiazai.php

<?php
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();

$sql = "select * from nation order by code ASC";
$arr = $db->Query($sql);

// 下面实现的字符串是类似这样的n001^汉族|n002^回族|n003^苗族
$str = "";返回主页面的数据是TEXT型，得转换一下
foreach($arr as $v)
{
    $str = $str.implode("^",$v)."|"; //拼接字符串
}
$str = substr($str,0,strlen($str)-1); //去掉末尾的|字符。
echo $str;

删除处理页面shanchu.php
