Question

I am using server side for getting photos from external url. I am using simple php dom library for getting this as per SO suggestion. But I am lacking performance in this. I mean for some sites I am not able to get all the photos.
$url has the example external site which is not giving me all the images.

  $url
  ="http://www.target.com/c/baby-baby-bath-bath-safety
  /-/N-5xtji#?lnk=nav_t_spc_3_inc_1_1";
  $html = file_get_contents($url);
  $doc = new DOMDocument();
  @$doc->loadHTML($html);
  $tags = $doc->getElementsByTagName('img');

  foreach ($tags as $tag) {
      echo $imageUrl = $tag->getAttribute('src');
   echo "<br />";
  }

Is this possible I can have functionality/accuracy similar to the option of Firefox

Firefox-> tools -> page info -> media

I mean I just want to be more accurate for this as the existing library is not fetching all images. Also I tried file_get_content…which is also not fetching all the images.

You need to use regular expressions to get images’ src. DOMDocument build all DOM structure in memory, You needn’t it. When You get URLs, use file_get_contents() and write data to files. Also add max_execution_time if You’ll parse many pages.
