请问数学建模2007B题的数据该怎么处理

哈哈,我做过了,VF代码

//定义一个新类
//实现公交换乘
class buss{
//定义数据库连接成员变量
var $host;
var $user;
var $passwd;
var $database;

//统计数据库中所有公交站点名,存入数组
//返回站点名

//返回站点名

$count = 0;
$result = mysql_query($SQL);
while($row = mysql_fetch_object($result)){

//统计经过某站点的所有公交车的组合
//需要参数station,表示经过的站点
//返回公交线路
function passline($station){

$count = 0;
$result = mysql_query($SQL);

//实现换乘算法的函数
//需要提供参数,查询的起点和终点
function bussStationToStation($start,$end){
$flag1 = false;
$flag2 = false;
//函数回调
$busstotal = $this->busstotal();
$busslinetotal = $this->busslinetotal();
//判断数据库中是否有此站点
for($i=0;$ipassline($end);
//得到经过起点和终点的线路的全部组合
$resultbus = "";
for($a=0;$abussperline($endpass[$b]);
for($c=0;$cbussStationToStation("火车站","五里墩");
//一切ok,直接就可以看到结果了
