解析html代码出现html错误问题

Question

我想解析链接： http://dizli.com/dizli/db.html 使用php。

但是当我编写代码时，

$url = "http://dizli.com/dizli/db.html";
$dom = new DOMDocument();
$html = $dom->loadHTMLFile($url);
$dom->preserveWhiteSpace = false; 
$tables = $dom->getElementsByTagName('table');
$tr = $tables->item(2)->getElementsByTagName('tr');
$rows = $tables->item(0)->getElementsByTagName('td');

foreach($rows as $row)
{
    $movie = $row->getElementsByTagName('b');
    echo $movie;}

我遇到了一堆错误：

有人可以帮我解析这个链接，以便我可以保存电影的名称和导演的名字。

Answer 1

要隐藏错误并仍然使用该代码，只需在 $dom 之前添加 @，例如：

$html = @$dom->loadHTMLFile($url);

Answer 2

该页面是用非常古老的 HTML 代码编写的（您可以通过 FONT 标签、大小写等来判断），因此
标签，可能还有段落和其他东西，都没有关闭。在这种情况下，我建议使用正则表达式来查找它们。

Answer 3

您的主要问题是最后一行：

echo $movie;

$movie 是 DOMNodeList 所以你不能只是回显它，你需要获取它的元素，例如 $movie->item(0)

你也可以只做一个$movie 的 var_dump 并看看会得到什么。

您可以忽略的警告取决于您得到的输出。
