Question

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

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;}

我收到了很多错误：

有人可以帮我解析这个链接，这样我就可以保存电影的名字和导演的名字。

Answer 1

要隐藏错误并仍然使用该代码，请在@之前添加广告$dom，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，大小写等来表示），因此＆lt; br＆gt;标签和可能的段落和其他东西也没有关闭。在这种情况下，我建议使用正则表达式来查找它们。

Answer 3

你的主要问题是最后一行：

echo $movie;

$movie是DOMNodeList的一个实例，所以你不能回应它，你需要获得它的元素，例如$movie->item(0)

你也可以var_dump $movie {{1}}，看看会给你带来什么。

您可能忽略的警告，取决于您获得的输出。
