What do you want the output to look like? I did this:
$num_pages =120;
if ($num_pages >= 2) {
for ($i=1; $i<=$num_pages; $i+=20) {
$page = $i+1;
printf("| <a href=\"test.php?page=%s\">Page %s</a> | ", $number, $page);
}
}
And got this:
| Page 2 | | Page 22 | | Page 42 | | Page 62 | | Page 82 | | Page 102 |

"If a man is called to be a streetsweeper, he should sweep streets even as
Michelangelo painted, or Beethoven composed music, or Shakespeare composed
poetry. He should sweep streets so well that all the hosts of heaven and
earth will pause to say, "Here lived a great streetsweeper who did his job
well." - Dr. Martin Luther King, Jr.
