Php 用于显示2组数据的Foreach循环配置

我使用简单的HTMLDOM从返回结果页面的网页中获取数据。我想把它格式化为标题，然后是描述。现在我正在使用以下代码：

<?php
include('simple_html_dom.php');
$html = file_get_html('https://www.example.com?q=randomquery');

foreach($html->find('div#resultscontainer') as $data)

//for each title
foreach($data->find('h3') as $title) {
//for each description
foreach($data->find('span.st') as $desc) {
//format code
    echo "<div class='result'>";
    echo $title;
    echo $desc;
    echo "</div>";
    }
}

?>

---

第二个foreach检查完整的HTML文件，而不是$title下面的内容

你应该这样做：

<?php
//for each title
foreach($data->find('h3') as $title) {
//for each description
foreach($title->parent->find('span.st') as $desc) {
//format code
    echo "<div class='result'>";
    echo $title->plaintext;
    echo $desc->plaintext;
    echo "</div>";
    }
}

foreach($html->find('div#resultscontainer') as $data) {
   $titlesAndDescriptions = array();

   // for each title
   foreach($data->find('h3') as $key => $title) {
      $titlesAndDescriptions[$key] = array('title' => $title);
   }

   // for each description
   foreach($data->find('span.st') as $key => $desc) {
      $titlesAndDescriptions[$key]['description'] = $desc;
   }

   foreach ($titlesAndDescriptions as $titleAndDescription) {
      echo "<div class='result'>";
      echo $titleAndDescription['title'];
      echo $titleAndDescription['description'];
      echo "</div>";
   }
}

像这样尝试：

<?php
//for each title
foreach($data->find('h3') as $title) {
//for each description
foreach($title->parent->find('span.st') as $desc) {
//format code
    echo "<div class='result'>";
    echo $title->plaintext;
    echo $desc->plaintext;
    echo "</div>";
    }
}

foreach($html->find('div#resultscontainer') as $data) {
   $titlesAndDescriptions = array();

   // for each title
   foreach($data->find('h3') as $key => $title) {
      $titlesAndDescriptions[$key] = array('title' => $title);
   }

   // for each description
   foreach($data->find('span.st') as $key => $desc) {
      $titlesAndDescriptions[$key]['description'] = $desc;
   }

   foreach ($titlesAndDescriptions as $titleAndDescription) {
      echo "<div class='result'>";
      echo $titleAndDescription['title'];
      echo $titleAndDescription['description'];
      echo "</div>";
   }
}

foreach（$html->find（'div#resultcontainer'）作为$data）{
$titlesAndDescriptions=array（）；
//每个标题
foreach（$data->find（'h3'）作为$key=>$title）{
$titlesAndDescriptions[$key]=数组（'title'=>$title）；
}
//每种描述
foreach（$data->find（'span.st'）作为$key=>$desc）{
$titlesAndDescriptions[$key]['description']=$desc；
}
foreach（$titleAndDescriptions作为$titleAndDescription）{
回声“；
echo$titleAndDescription['title']；
echo$titleAndDescription['description']；
回声“；
}
}
您应该至少添加有问题的标记，或者添加live url（如果可以的话），没有人会发现这段代码有什么问题code@Ghost我正在从谷歌获取结果。获取数据并不难，我在获取数据后遇到格式化问题。最后一个
foreach
应该在第二个之外。@MateiMihai这不起作用，因为顶部会有一大块标题，而描述仍然在底部。我想问的是如何将标题与描述按顺序匹配。谢谢。我更喜欢这个答案，因为它允许我更容易地扩展我想要分离的数据。
