Limiting bootstrap pagination in PHP to 5 pages - php

Question

I'm trying to create pagination in PHP where 5 pages are displayed.
When on the first page we have:
[1][2][3][4][5] ...[325][>>]
Clicking on [325] will take you to that page (the last record), clicking on the right arrow will take you to page [2].
When on the second page we have:
[<<][1]...[2][3][4][5][6] ...[325][>>]
And when on the last page we have:
[<<][1]...[321][322][323][324][325]
I've been researching on how to do this without much luck. I think I understand that I need to create an array with adjacent pages of 2 on each side of the active page, when we are on any page except the first or last page. I also need to create an <li>1</li>
and
<li><?php echo $last_record; ?></li>
for when a user is anywhere but the first or last record.
I have the following code which works great, however when we start getting a large number of records, the pagination count gets ridiculous.
<ul class="pagination pull-left pagination-md">
<?php
// Creates back button in pagination
if(isset($page)) {
if($page > 1) {
$page_minus = $page-1;
echo "<li><a href='blog.php?page=$page_minus'> « </a></li>";
}
}
?>
<?php
global $con;
$q_pagination = mysqli_prepare($con, "SELECT COUNT(*) FROM admin_panel WHERE ");
$q_pagination->execute();
$result_pagination = $q_pagination->get_result();
$rows_result = $result_pagination->fetch_array();
$total_rows = array_shift($rows_result);
$post_per_page = $total_rows/15;
$post_per_page = ceil($post_per_page);
for($i = 1; $i <= $post_per_page; $i++) {
if(isset($page)){
if($i == $page) {
echo "<li class='active'><a href='blog.php?page=$i'>$i</a></li>";
}
else {
echo "<li><a href='blog.php?page=$i'>$i</a></li>";
}
}
}
// Creates the forward button in pagination
if(isset($page)){
if($page+1 <= $post_per_page) {
$page_plus = $page+1;
echo "<li><a href='blog.php?page=$page_plus'> » </a></li>";
}
}
?>
</ul>
I'll admit, after researching and attempting to make this work I'm just getting twisted in the logic. Does anyone have any thoughts on how to best approach this? Leads, current examples, etc. Most of what I've found is dated, incomplete, or stupid long.
