如何使用param查找对象标记，并使用简单的htmlDOMphp将标记嵌入HTML中 - How to find object tag with param, and embed tag inside HTML using simple html DOM php

我发现很难理解php的简单html dom。即使我读了关于如何做的说明。对我来说，我只是编程行业的新手。由于我一直在寻找如何找到对象标签和嵌入，我找不到正确的答案。因此，我将在这里发布我的问题，并希望得到正确的答案。：）

我找不到这样的对象：http://vodlocker.com/embed-gu09418zgs6y.html

这是来自vodlocker页面源的带有param的对象标记。这就是我想要得到的。

<object type="application/x-shockwave-flash" data="http://vodlocker.com/player/player.swf" width="100%" height="100%" bgcolor="#000000" id="flvplayer" name="flvplayer" tabindex="0" __idm_id__="937985">

</object>

这是我的密码。这不起作用。我不知道为什么。也在其他包含嵌入的网站上。它也不起作用。

include "include/simple_html_dom.php";
$a = "http://vodlocker.com/embed-gu09418zgs6y.html";
$html = file_get_html($a);
$b = $html->find('object')[0];
echo $b;

我认为您的问题是$b = $html->find('object')[0];。尽管这在许多语言中都有效，但在5.4以下的PHP版本上却不起作用。改为：

$b = $html->find('object'); $b = $b[0];

就我个人而言，我使用DOMDocument:

$dom = new DOMDocument;
@$dom->loadHTMLFile('http://vodlocker.com/embed-gu09418zgs6y.html');
if($objs = $dom->getElementsByTagName('object')){
  foreach($objs as $o){
    // $o is each <object> $objectHTML[] = $dom->saveHTML($o);
    foreach($o->childNodes as $p){
      if(preg_match('/^param$/i', $p->nodeName)){
        // $p is each <param> in loop
      }
    }
  }
}

在我注释掉$objectHTML[] = $dom->saveHTML($o);的地方，$objectHTML数组将以HTML形式包含每个对象。$objectHTML[0]将是第一个对象标记，其内容为HTML。

看起来有两个问题。首先，我相信你想要的是：

$b = $html->find('object', 0);

根据文档，这就是如何查找<object>标记的第一个实例。

不过，您的第二个问题是$html不返回任何带有<object>标记的代码——您正在搜索的代码块不在那里。

如果您要查找的是http://95.211.193.83:8777/k6ceg4duoo4pcnokaktshz6a5e6vcg4hy7lzvwxjtd7ddxdeooarqi7uci/v.mp4值，则它嵌入在标头中的<script>标记中，因此请尝试：

$b = $html->find('script');

然后循环遍历$b返回的数组，直到得到所需内容。
