您需要熟悉 DOMDocument class.执行此操作的最佳方法是使用DOMDocument解析HTML,并找到所有< img>标签使用getelementsbytagname(‘img’).如果它是你所追求的图像的src属性,DOMDocument可以返回它们并存储在数组中.

// HTML already parsed into $dom
$imgs = $dom->getElementsByTagName('img');
$img_src = array();

// Array of nodes to remove.
$to_remove = array();

foreach ($imgs as $img) {
  // Store the img src
  $img_src[] = $img->getAttribute('src');

  // Delete the node (I think this works)
  $to_remove[] = $img;
}

// Then remove all the nodes slated for deletion:
foreach ($to_remove as $node) {
  $dom->removeChild($img);
}
