But it looks ugly so i thought someone has better solution

and i need somehow to place it under the server list

Answer 1

The simplest way to make pagination is to COUNT the total number of rows, and then add a LIMIT to it.
Count the rows:
SELECT COUNT(*) WHERE `disabled`=0 ORDER BY `cache_time` ASC;
Then add your limit:
SELECT `type`,`ip`,`c_port`,`q_port`,`s_port` FROM `{$lgsl_config['db']['prefix']}{$lgsl_config['db']['table']}` WHERE `disabled`=0 ORDER BY `cache_time` ASC LIMIT $start, $perpage;
Where $perpage=20; or any number you would like and $start=(int)$_GET['page']*$perpage;
Simply add links at the bottom for each of the pages you would like to display:
for($a=0;$a<$rows;$a++){
echo"<a href='table.php?page=$a'>$a</a>";
}
That is the gist of it anyways to get you started.

Answer 2

To paginate the mysql query, add a limit clause
LIMIT $begin, $end
Where:
$begin = ($page_num-1)*$NUM_PER_PAGE;
$end = $begin + $NUM_PER_PAGE;
