PHP Pagination links increment - php

Question

Basically i want to limit the amount of numbers displayed on my page, but currently it's displaying 31 numbers, because their is 31 pages of results, i'd like to show 5 links and just increment after every page,
Here's how they're currently being displayed
[1] [2] [3] [4] [5] [6] [7] [8] etc..
Here's what i'd like
[1] [2] [3] [4] [5]
What i'd like i just but once you select for example number 8, it'd place that number in the middle and 2 links either side for example like this
[6] [7] [8] [9] [10]
Here's the current code that i'm using
function showPageNumbers($totalrows,$page,$limit){
$query_string = $this->queryString();
$pagination_links = null;
$numofpages = $totalrows / $limit;
for($i = 1; $i <= $numofpages; $i++){
if($i == $page){
$pagination_links .= '<li class="active">'.$i.'</li>';
}else{
$pagination_links .= '<li>'.$i.'</li>';
}
}
if(($totalrows % $limit) != 0){
if($i == $page){
$pagination_links .= '<li class="active">'.$i.'</li>';
}else{
$pagination_links .= '<li>'.$i.'</li>';
}
}
return $pagination_links;
}

You can have modified function like:
function showPageNumbers($totalrows, $page, $limit){
$query_string = $this->queryString();
$pagination_links = null;
$numofpages = $totalrows / $limit;
$linksPerPage = 5;
$firstNum = $page - round(($linksPerPage)/2);
if($firstNum < 1)
$firstNum =1;
$lastNum = $firstNum + $linksPerPage -1;
if($lastNum > $numofpages)
$lastNum = $numofpages;
for($i = $firstNum; $i <= $lastNum; $i++){
if($i == $page){
$pagination_links .= '<li class="active">'.$i.'</li>';
}else{
$pagination_links .= '<li>'.$i.'</li>';
}
}
return $pagination_links;
}
