Question

我想在周末学习一些新东西并决定自学PHP，DOM和MySQL。作为一个开始的项目，我想尝试将我从其他网站中提取的下表添加到我自己的数据库中。

Extract http://i67.tinypic.com/fuot5g.jpg http://i67.tinypic.com/fuot5g.jpg

但是，当我尝试将数据（不包括'No.'，'Ticker'等标题行）添加到我自己的数据库中时，我碰到了一堵墙。

以下是我的代码摘录：

<?php   

     $dom = new DOMDocument;
     $dom->loadHTML($document);

     $tbl = $dom->getElementByID('forex_performance');
     $trneeded = $tbl->getElementsByTagName('tr');

     foreach ($trneeded as $row) {
         foreach ($row->getElementsByTagName('td') as $cell) {
              $cellarray[] = $cell->nodeValue;
              $query = "INSERT INTO sampletable (no, ticker, price, perf5, perfhour, perfday, perfweek, perfmonth,perfquart, perfhalf, perfyear, perfytd, date, time) VALUES ('')
              mysql_query($query);
        } 
     }

?>

我能够从单元格数组中获取特定数据，但我不能在我的生活中找出如何将它们插入到我的数据库中。

我还是很陌生，希望我的问题有道理！如果有人能指点我正确的方向，我真的很感激！
