使用方法-PHP教程,PHP应用

这是我当时写的一个列出所有购物车中的清单的程序，各位可自己根据需要改写一下
<?php
    ob_start();
    session_start()                 ;
/*
    $s=array("id" => 6, "name" => "测试a", "price" => "6", "count" =>3);
    $t=array("id" => 7, "name" => "测试b", "price" => "7", "count" =>15);
    $u=array("id" => 8, "name" => "测试c", "price" => "8", "count" =>21);
    $rst=array($s, $t, $u);

    */
    require_once("html/it.php");
    $tpl    = new html_template_it("./");
    //读取模板文件           
    $tpl->setroot("./");
    $tpl->loadtemplatefile("listcart.html", true, true);
    require_once "../classes/cart.php" ;
    $cart = new cart   ;
//    $cart->adddata($rst);
    $i=count($_post[lines])    ;
    if($_post["emptyall"]==true)
    {
        //如果清空条件为真
        $cart->emptyall()    ;
    }else{
        //如果用户提交更新
        if( $i > 0)
        {
            //如果提交过来的数据大于一个商品
            $adddata = $_post[lines]    ;
            foreach($adddata as $key=>$val)
            {
                if($val["del"]==true)
                {    
                    $cart->emptyone($key)        ;
                    unset($adddata[$key])            ;
                }
            }
            $cart->adddata($adddata)    ;
        }
    }
    $dat = $cart->getdata();
    if(count($dat) > 0)
    {
        foreach($dat as $key=>$val)
        {        
            $tpl->setcurrentblock("lines") ;

ob_end_flush();
