Pagination for a different number of posts Wordpress

The number of posts on the page is regulated by settings in the admin panel of the site.

But how to turn on navigation for different numbers of posts on different pages? Let’s find out!

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'entry' ); ?>

<?php echo paginate_links() ?> //navigation function

<?php endwhile; endif; ?>

To change the number of post on one page and enable pagination, we need to create a new WP_Query and transfer the number of posts to for output.

<?php

$paged = '';

if(is_singular()) {
  $paged = (get_query_var('page')) ? get_query_var('page') : 1; 
}else{
  $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
}

$newnumberofposts = new WP_Query(array(
'post_type'=>'post', 
'post_per_page'=>5, //number of entries per page
'paged' => $paged
)
);
?>

<?php if ( $newnumberofposts->have_posts() ) : while ( $newnumberofposts->have_posts() ) : $newnumberofposts->the_post(); ?>
<?php get_template_part( 'entry' ); ?>

<!-- Pagination -->
<?php 
$bignumber = 9999999999; //

echo paginate_links(array(
    'base' => str_replace($bignumber, '%#%', esc_url(get_pagenum_link($bignumber))),
    'format' => '?paged=%#%',
    'current' => max(1, get_query_var('paged')),
    'total' => $newnumberofposts->max_num_pages
));
?>

<?php endwhile; endif; wp_reset_postdata(); ?>
