對於每個只有幾個記錄重複數百次

我使用php簡單dom解析器屏幕刮板，我試圖設置它來刮擦頁面的內容。問題是它將數據拉好，但它一遍又一遍地重複着，我無法弄清楚爲什麼。看來每個記錄都被重複了好幾次。對於每個只有幾個記錄重複數百次

<?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> 
    '; 
    ?>

頁從它的拼搶是在這裏： http://www.goldengrovenursery.co.uk/griffin_x/results.asp?txtgenus=Chamaecyparis&txtcultivar=&txtcolour=All&Search=Availability&offset=40

上述腳本結束這樣看，即使只有10個記錄的頁面上：

你」呃用你的第二個foreach()循環搜索整個文檔cultivar，而不是簡單的genus，你已經找到了第一個foreach();同樣地，對於species內cultivar

但因爲每個條目實際上是在其自己的行中嵌套表，還需要通過DOM每個條目走回頭路了起來：

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)

更好的變量命名也可能說明清楚：

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嘗試了上面的內容，但這只是給了我一個只有表頭的空白頁面。 –

查看我編輯的編輯 –

問題是，每個項目都返回一個數組，所以我得到10x屬，10x品種和10x物種，我需要做的是逐行打印出來。 –

檢查該解決方案

    echo "<div style='float:left'>";
