如何从其他站点获取图像源？ [关闭]

Question

I had so many web site addresses which have images I want to have. I want to know the image source at that web site.

Below is my php code. but that doesn't work.

  <?php
  $html = array('url1', 'url2', ...);
  $result = "";
  preg_match_all('/<img[^>]+>/i', $html, $result);
  echo $result;
  ?>

Please, Would you complete above incomplete code?

You better off with DOMDocument Class , Never use Regex as a parser for parsing HTML Content.

$htmlsourceofthewebsite = file_get_contents('http://www.somewebsite.com');
$dom = new DOMDocument;
$dom->loadHTML($htmlsourceofthewebsite);
foreach ($dom->getElementsByTagName('img') as $tag) {
        echo $tag->getAttribute('src');
    }
}
