对于每个只有几个记录重复数百次

我使用php简单dom解析器屏幕刮板，我试图设置它来刮擦页面的内容。问题是它将数据拉好，但它一遍又一遍地重复着，我无法弄清楚为什么。看来每个记录都被重复了好几次。对于每个只有几个记录重复数百次

<?php 
    // example of how to use basic selector to retrieve HTML contents 
    include('../simple_html_dom.php'); 

    // get DOM from URL or file 
    $html = file_get_html('http://www.goldengrovenursery.co.uk/griffin_x/results.asp?txtgenus=Chamaecyparis&txtcultivar=&txtcolour=All&Search=Availability&offset=40'); 



    echo '<table> 
    <thead><th>Genus</th><th>Cultivar</th></thead> 
    <tbody>'; 
    foreach($html->find('td.genus') as $a) 
    foreach($html->find('td.cultivar') as $b) 
    foreach($html->find('td.species') as $c) 
     echo '<tr><td>'.$a->innertext.'</td><td>'.$b->innertext.'</td><td>'.$c->innertext.'</td></tr>'; 
    echo '</tbody> 
    </table> 
    '; 
    ?>

页从它的拼抢是在这里： http://www.goldengrovenursery.co.uk/griffin_x/results.asp?txtgenus=Chamaecyparis&txtcultivar=&txtcolour=All&Search=Availability&offset=40

上述脚本结束这样看，即使只有10个记录的页面上：

你”呃用你的第二个foreach()循环搜索整个文档cultivar，而不是简单的genus，你已经找到了第一个foreach();同样地，对于species内cultivar

但因为每个条目实际上是在其自己的行中嵌套表，还需要通过DOM每个条目走回头路了起来：

foreach($html->find('td.genus') as $a) 
foreach($a->parent()->parent()->find('td.cultivar') as $b) 
foreach($b->parent()->parent()->find('td.species') as $c)

更好的变量命名也可能说明清楚：

foreach($html->find('td.genus') as $genus) { 
    foreach($genus->parent()->parent()->find('td.cultivar') as $cultivar) { 
     foreach($cultivar->parent()->parent()->find('td.species') as $species) { 
      echo '<tr><td>' . 
       $genus->innertext . 
       '</td><td>' . 
       $cultivar->innertext . 
       '</td><td>' . 
       $species->innertext. 
       '</td></tr>'; 
     } 
    } 
}

Iv尝试了上面的内容，但这只是给了我一个只有表头的空白页面。 –

查看我编辑的编辑 –

问题是，每个项目都返回一个数组，所以我得到10x属，10x品种和10x物种，我需要做的是逐行打印出来。 –
