Could you please tell me how to output the latest data on the front page of the front-end article list page in the pagination section, and then proceed in reverse order? If you click on the news page, the home page will display the latest data.

I figured it out by myself, put this /* to get the value offset of the first parameter of limit, if the first page is (1-1)*10=0, the second page is (2-1)* 10=10. (Number of pages passed in - 1) * The data on each page gets the value of the first parameter of limit */
$sql="select * from article limit $offset,$num "; Just change it to the following one Ahaha
$sql="select * from article order by id desc limit $offset,$num ";

<?php
//Paging function
//Connect to database
require_once("connect.php");
$page = isset($_GET['page'])? intval($_GET['page']):1;//Set the current page number, if not, set it to 1
$num=3;//Display 3 pieces of data per page
/*
First We need to get how much data there is in the database to determine how many pages it needs to be divided into. The specific formula for the total number of pages is
The total number of data divided by the number of items displayed on each page, and the remainder is one.
That is to say, 10/3=3.3333=4 If there is a remainder, we must round it up by one.
*/
$sql="select * from article";
$result=mysqli_query($conn,$sql);
$total=mysqli_num_rows($result);//query data Total number of entries
$pagenum=ceil($total/$num);//Get the total number of pages
//If the page parameter passed in is greater than the total page number pagenum, an error message will be displayed
if($page>$pagenum || $page == 0){
echo "<script>alert('No more content');history.go(-1);</script>";
exit;
}
$offset=($page-1)*$num;
/* Get the value offset of the first parameter of limit, if the first page is (1-1 )*10=0, the second page is (2-1)*10=10. (Number of pages passed in - 1) * The data of each page gets the value of the first parameter of limit */
$sql="select * from article limit $offset,$num ";
$info=mysqli_query ($conn,$sql); //Get the data that needs to be displayed for the corresponding page number
//Get the first six newly added data
$sql_new="select id,title from article order by dateline desc limit 0 ,6 ";
$info_title=mysqli_query($conn,$sql_new);
?>
