php pagination with break or continue

I need to make a paging with this format:

1 2 3 4 5 ... 205

i use now this for loop:

$nav = '';
for($pageNum = 1; $pageNum <= $maxPage; $pageNum++)
{
   if 开发者_运维百科($pageNum == $p)
   {
   $nav .= '<li class=\"current\">$pageNum</li>';
   }
   else
   {
   $nav .= '<li><a href=\"?page=".$pageNum."\">$pageNum</a></li>';
   }
}

i need to use a php break or continue??
