php - 简单的 HTML DOM 解析器 - 在 foreach 循环中显示变量时出现问题

问题描述

我使用 simple_html_dom.php 类创建了一个简单的 PHP 脚本。我从网站上获取一些关于电影的信息。我在另一个 foreach 循环中有一个 foreach 循环。当我尝试在 foreach 循环中显示电影名称时，我得到了最后一个电影名称。我想要实现的是在每个项目中获取每个唯一的电影名称。问题在于 $movie 变量。

（当我在第 27 行回显 $movie var 时，我得到了正确的结果，但我希望在第 33 行的 youtube 链接中包含每个电影名称……）

<?php
include("simple_html_dom.php");
    
$tpb = 'https://tpb.party/search/2020/1/99/200';
$html = file_get_html(html_entity_decode($tpb));
    
foreach($html->find('tr.header') as $header) {
    $header->outertext = '';
}
        
foreach($html->find('td') as $bottom) {
    if ($bottom->colspan == '9') {
        $bottom->outertext = '';
    }
}
        
foreach($html->find('td.vertTh') as $vert) {
    $vert->outertext = '';
}   
    
foreach($html->find("div.detName") as $movie) {
    $movie = $movie->plaintext;
    echo $movie;    //Works Okey, it displays each of the movietitles
    
    foreach($html->find('img') as $img) {
    
        if ($img->outertext == '<img src="https://tpb.party/static/img/11x11p.png" height="11" width="11">') {
            $img->outertext = '&nbsp;&nbsp;<a href="https://www.youtube.com/results?search_query='. $movie /* Doesn't work, only displays one title, not one each of the 30*/ .'" target="_blank"><img src="img/youtube.png" alt="Trailer" title="Trailer" style="width:19px;" width="19" height="18" border="0"></a>';
        }
    }
}   
    
$html->save();
foreach($html->find("table") as $title) {
    echo $title->outertext . '<br>';
}
?>

现在怎么样了：

替换 IMG 元素的 HTML 代码和问题是所有元素的链接都是相同的，当它们对于每个元素（如 MovieTitles）应该是唯一的时：

<td>
  <div class="detName"> <a href="https://tpb.party/torrent/37614340/The.Mandalorian.S02E05.Chapter.13.The.Jedi.2020.1080p.WEB-DL.X26" class="detLink" title="Details for The.Mandalorian.S02E05.Chapter.13.The.Jedi.2020.1080p.WEB-DL.X26">The.Mandalorian.S02E05.Chapter.13.The.Jedi.2020.1080p.WEB-DL.X26</a>

解决方案

您想要的图像嵌套在detNameDIV 的同级之一中。因此，您可以通过在父元素中搜索来搜索它。

由于find()允许更复杂的 CSS 选择器，您可以专门搜索您想要的图像，而不是遍历所有图像。

foreach($html->find("div.detName") as $movieDiv) {
    $movie = $movieDiv->plaintext;
    echo $movie;    //Works Okey, it displays each of the movietitles
    
    $img = $movieDiv->parent()->find('img[src="https://tpb.party/static/img/11x11p.png"]', 0);
    if ($img) {
        $img->outertext = '&nbsp;&nbsp;<a href="https://www.youtube.com/results?search_query='. $movie .'" target="_blank"><img src="img/youtube.png" alt="Trailer" title="Trailer" style="width:19px;" width="19" height="18" border="0"></a>';
    }
}
