【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。问题出在 $movie 变量上。
（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 = ' <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>';
}
?>

</td>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，而对于每个元素，如 MovieTitles，它们应该是唯一的：
<td>

</td>【问题讨论】：
-
$html->find('img') 的大小是多少？
-
@RafaelDouradoD 它获取 30 个项目并显示它们，30 个带有图像的标题。
-
foreach($html->find('img') as $img)循环正在替换页面中每部电影的所有图像。所以对于第一部电影，它将用<a ...search_query=movie1><img ...></a>替换<img ...>，然后下一部电影将用<a ... search_query=movie1><a ... search_query=movie2><img ...></a></a>替换它。每次迭代都会嵌套一次。 -
我怀疑您只想替换同一 DIV 中的图像，而不是整个页面上的所有图像。
-
@Barmar 这就是它的样子：i.postimg.cc/hvPvRzJM/tpbscr.png 我基本上是用 youtube 图标替换所有空图像。这个想法是，当您单击 youtube 图标时，您会被发送到 youtube.com/results?search_query=MOVIE+Trailer
