For some reason, some times with cURL find the pages but not other times, instead simple_html_dom find the page with same url.
For example:
$url = http://www.youtube.com/results?search_type=search_users&search_query=java&page=7
with cURL the page is not foud:
$curl = curl_init();
curl_setopt($curl, CURLOPT_REFERER, $url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec( $curl );
curl_close($curl);
if(strpos($content, "404") || $content==""){ echo "**************** PAGE NOT FOUND ****************\n"; return;}
but yes with html_simple_dom:
$content = file_get_html($url);//same url above
