smart PHP Pagination - php

Question

I want to split pages to make it more smart and look nice,
I use this code to make Pagination
if (!isset($_GET['page'])){
$page = 1;
}
else {
$page = intval($_GET['page']);
}
$numbershownews = 1;
$x = ($page-1)*$numbershownews;
$select_news_all = $mysqli->query("SELECT id FROM news where FIND_IN_SET('$id_newscats_cat', cats) order by time desc");
$num_news_all = $select_news_all->num_rows;
$cn = $num_news_all/$numbershownews;
$select_news = $mysqli->query("SELECT * FROM news where FIND_IN_SET('$id_newscats_cat', cats) order by time desc limit $x,$numbershownews");
while ($rows_news = $select_news->fetch_array(MYSQL_ASSOC)){
$id_news = $rows_news ['id'];
$title_news = $rows_news ['title'];
}
i show pages by this code
<?
$pagenext = $page+1;
$pageprev = $page-1;
?>
<ul>
<li>
<?
if (($page == 1) or ($page == "")){
?>
<i class="fa fa-angle-double-right"></i>
<?
}else{
?>
<a class="link" href="<? echo "{$newurltitle_newscats_cat}-c-{$id_newscats_cat}-p-{$pageprev}.html"; ?>"><i class="fa fa-angle-double-right"></i></a>
<?
}
?>
</li>
<?php
for($i=0; $i<$cn; $i++){
$pagenumber = $i+1;
if($page == $pagenumber){
echo "<li>{$pagenumber}</li>";
}else{
?>
<li><a class="link" href="<? echo "{$newurltitle_newscats_cat}-c-{$id_newscats_cat}-p-{$pagenumber}.html"; ?>"><? echo $pagenumber; ?></a></li>
<?
}
}
?>
<li>
<?
if($page >= $cn){
?>
<i class="fa fa-angle-double-left"></i>
<?
}else{
?>
<a class="link" href="<? echo "{$newurltitle_newscats_cat}-c-{$id_newscats_cat}-p-{$pagenext}.html"; ?>"><i class="fa fa-angle-double-left"></i></a>
<?
}
?>
