Plugin Pagination help…

There is pagination on a plugin I’m using and I not getting any response from the writer. It’s not a pluign I downloaded from this site.

Basically I just want to find out how to display the pagination like this:
<< 1 2 3 4 … 20 >>

It would be great if anyone could help. Thanks in advance.

Here is the code:

$pr = get_option('frp_rpp'); // rows per page
	$page = isset($_GET['page']) ? (int) $_GET['page'] : 1;

	// BEGIN PAGINATION HEAD
	if($competition != '')
		$pages = implode(mysql_fetch_assoc(mysql_query("SELECT COUNT(*) FROM <code>$tbl_match</code> WHERE DATE_ADD(matchdate, INTERVAL matchtime HOUR_SECOND) <= NOW() AND competitionyear = '$year' AND competition = '$competition' ORDER BY matchdate DESC")));
	if($competition == '')
		$pages = implode(mysql_fetch_assoc(mysql_query("SELECT COUNT(*) FROM <code>$tbl_match</code> WHERE DATE_ADD(matchdate, INTERVAL matchtime HOUR_SECOND) <= NOW() AND competitionyear = '$year' ORDER BY matchdate DESC")));

	$pages = ceil($pages/$pr);

	$querystring = '';
	foreach($_GET as $key => $value) {
		if($key != "page") $querystring .= "$key=$value&";
	}
	// END PAGINATION HEAD

	// BEGIN PAGINATION DISPLAY
	// TODO: CHECK FOR MORE THAN 1 PAGE
	if($pages > 1) {
		$display .= '<p class="pagination"><strong>Results:</strong> ';
		for($i = 1; $i <= $pages; $i++) {
			$display .= '<a '.($i == $page ? 'class="selected" ' : '');
			$display .= "href=\"?{$querystring}page=$i";
			$display .= '">'.$i.'</a> ';
		}
		$display .= '</p>';
	}
	// END PAGINATION DISPLAY
