How to limit pages in pagination in php - php

Question

i want to make the pages not go beyond 10
this the code that shows the number of pages
for ($page=1;$page<=$number_of_pages;$page++) {
echo '' . $page . ' ';
}`
this is the output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
and i want to make it go like this
1 2 3 4 5 6 7 8 9 10 ...
and if im on page 10 it will show like this
1 .. 10 11 12 13 14 15 16 17 18 19 20 ... 25
i don't have any idea how to make this work
this is the source
<?php

$sql="SELECT * FROM books_data WHERE Book_Title LIKE '%$KW%' OR Book_Author
LIKE '%$KW%' ORDER BY Book_Title";
$result = mysqli_query($connect, $sql);
$number_of_results = mysqli_num_rows($result);
$number_of_pages = ceil($number_of_results/$results_per_page);
if (!isset($_GET['page'])) {
$page = 1;
} else {
$page = $_GET['page'];

try the following:
function pageList($pages, $current_page)
{
$output = '';
$previous_page = 0;
foreach($pages as $page)
{
if ($page - $previous_page > 2)
{
$output.= '... ';
}
else
if ($page - $previous_page === 2)
{
$output.= '... ';
}
$output.= "$page ";
$previous_page = $page;
}
return $output;
}
function createPagination($current_page, $number_of_pages)
{
$page_span = 5;
$middle_min = max($current_page - $page_span, 1);
$middle_max = min($current_page + $page_span, $number_of_pages);
$pages = range($middle_min, $middle_max);
if ($middle_min !== 1)
{
array_unshift($pages, 1);
}
if ($middle_max !== $number_of_pages)
{
$pages[] = $number_of_pages;
}
return pageList($pages, $current_page);
}
$current_page = isset($_GET['page']) ? $_GET['page'] : 1;
$number_of_pages = 25;
echo createPagination($current_page, $number_of_pages);
This will dispaly the 5 pages before and after of the selected page. Just edit the $page_span to determine how many of the pages you want to show. This uses a simple loop to loop over range of values from the minimum to maximum range.
