What you're looking for is called pagination. There's a tutorial on the main site.

I made 2 types of pagination.

 

The first can do any posts amount, the second I hardcoded set to 10 posts per page, takes more math to predetermine the pages which I didn't need

 

can see them both working and the codes embed below them.

and this

Basically it controls the limit in a mysql query determined by what current page you are on

i'm assuming you know how to paginate your data and simply want to know how to the create the page links. i wrote the function below. simply pass in the current page number, the total number of pages and the url to go to when each page is clicked. the function appends a page variable, pg, to the end of url. it returns the HTML for the page numbers.

 

public function pageLinks($pageNumber, $pageCount, $url) {
  
    $pl = "Total Pages: $pageCount<br/>";
    $multiples = ceil($pageCount / 10);
    $theMultiple = ceil($pageNumber / 10);
    $qSep = strpos($url, '?') ? '&' : '?';
   

    // newer elements available?
    if ($theMultiple > 2) {
      $pl .= "<a href='${url}${qSep}pg=1'>< Newest</a>  ";
    }
    if ($theMultiple > 1) {
      $pl .= "<a href='${url}${qSep}pg=" . ((($theMultiple-2) * 10) + 1) . "'>< Newer</a>  ";
    }

    // current multiple
    $startPage = (($theMultiple - 1) * 10) + 1;
    $endPage = min($theMultiple * 10, $pageCount);
    for ($i = $startPage; $i <= $endPage; $i++) {
      $pl .= " " . (($pageNumber == $i) ? "<b>$i</b>" : "<a href='${url}${qSep}pg=$i'>$i</a>");
    }
    $pl .= "  ";


    // older elements available?
    if ($theMultiple < $multiples) {
      $nextMultiple = ($theMultiple * 10) + 1;
      $pl .= "<a href='${url}${qSep}pg=" . $nextMultiple . "'>Older ></a>  ";
    }
    if ($theMultiple < $multiples - 1) {
      $pl .= "<a href='${url}${qSep}pg=$pageCount'>Oldest ></a>";
    }

    return $pl;
  } // pageLinks
