Question

I want to fetch a certain link at every 30 seconds interval and parse it’s code in my program. Is there a way to do this?

I need to obtain certain things found in it’s code that always change at fixed intervals.

I’ve tried using an iframe and getting it’s innerHTML but that doesn’t work also php’s file_get_contents() doesn’t work.

Answer 1

Could you try using this?
http://davidwalsh.name/download-urls-content-php-curl

The code

 /* gets the data from a URL */
function get_data($url)
{
  $ch = curl_init();
  $timeout = 5;
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
  $data = curl_exec($ch);
  curl_close($ch);
  return $data;
}

Then call with

$returned_content = get_data('http://davidwalsh.name');
