session_start() [function.session-start]:
我看到在这个问题上前面的问题,可是,仍然不能确定我的错误。
假设是错误家伙?
<?
php
session_start();
      if ($_POST['add'])
      {
            foreach ($_POST['a_qty'] as $k => $v)
            {
                  $_SESSION['cart'][$k] = $_SESSION['cart'][$k] + $v;
            }
      }
?>
<?php
// look for catalog file
      $catalogfile = "catalog.dat";
      // file is avaialbe, extract data from it and place into $catalog, with sku as key
      if (file_exists($catalogfile))
      {
            $data = file($catalogfile);
            foreach ($data as $line)
            {
                  $lineArray = explode(":", $line);
                  $sku = trim($lineArray[0]);
                  $CATALOG[$sku]['desc'] = trim($lineArray[1]);
     (www.111cn.net)             $CATALOG[$sku]['price'] = trim($lineArray[2]);                              
            }
      }
      else
      {
            die("Could not find the catalog file");
      }
?

<table border="1" cellspacing="10">
<?
php
            // print items from the catalog for selection
            foreach ($CATALOG as $k => $v)
            {
