You should receive permission from the auction site, if you don't already have it. file() or file_get_contents() along with the use of preg_match() to find what you're looking for should do you some good.

i have written a small function to parse pages. hope that will help you.

Code: Select all

function str_between($str,$start,$end) {
  if (preg_match_all('#' . preg_quote($start) . '(.*?)' . preg_quote($end) . '#s',$str,$matches)) {
   return $matches[1];
  }
  // no matches
  return false;
}
use it like this

Code: Select all

$data_mac = file_get_contents("http://www.yoururl.com/");
//die();
$start='<td valign="top" class="details">';
$end='<p class="availability">';

$arr_data=str_between($data_mac,$start,$end);
$arr_data will have all the returned results in an array. :D
