PHP development article publishing system front-end article list page
The general layout of the front-end article list page is as follows:
## In the first chapter, we have already shown the static page of the front-end list page. In this chapter, we will use PHP to make it a dynamic page.
The flow chart of the front-end list program is as follows:
##The code is as follows:
<?php
//引入分页程序
require_once("../paging.php");
//取出列表页3条数据,存于数组$data中
if($info&&mysqli_num_rows($info)){
while($row=mysqli_fetch_assoc($info)){
$data[]=$row;
}
}else{
$data=array();
}
//取最新添加的6条编号、标题信息,存于数组$data_title
if($info_title&&mysqli_num_rows($info_title)){
while($row_title=mysqli_fetch_assoc($info_title)){
$data_title[]=$row_title;
}
}else{
$data_title=array();
}
?>

Code Comments
- The PHP code added is mainly to display the data queried in the paging program in a loop
- The paging part mainly calculates the value of the new $page through the $page of the current page. Click on the previous page or next page to calculate the value of the new $page and pass it to the paging processing program. The paging program will calculate the value of the new $page based on the $page. page, re-fetch the corresponding page information from the data set
- The comments in the program part are very clear, you can copy it locally and test it yourself
