Can anyone please suggest me the code which will fix this issue? i am quite noob to php :( only good at CSS and Photoshop.

Thanks in Advance.

You can add exception handling around it, so if it fails, it does nothing.

@pritaeas : Thanks, unfortunately i am not quite sure how to do that, if not asking too much,, can you please suggest me the code to do that? Thanks again for the quick reply.

Something like this:

foreach ($urls as $key => $url) {
    $url = trim($url);

    try {
      $html = file_get_html($url);

      $ep = $html->find('.post-container img');
      $data .= $ep[0]->src . "\n"; 
    }
    catch (Exception $e) {
        echo "Error parsing url: $url<br/>";
    }
}

Aha. file_get_html is not a built-in PHP function. Did you download the package it belongs to?
