The approximate layout of the page is as follows:
Layout introduction
We have shown the front-end interface before, which is a static page. This summary adds PHP code to dynamically read database information
The front-end layout of the page mainly uses DIV+CSS to draw When creating a table, you can actually achieve this effect by using the <table> tag. You should mainly pay attention to the implementation of the function
The code is as follows:
<?php
//连接数据库
require_once("../connect.php");
$SQL="SELECT * FROM article ORDER BY dateline DESC";
//执行查询语句
$query=mysqli_query($conn,$SQL);
//判断查询语句是否查询到结果，查到则使用mysqli_fetch_assoc()将其逐行取出，放入数组$data中，没查到则直接赋值空数组给$data
if($query&&mysqli_num_rows($query)){
while($row=mysqli_fetch_assoc($query)){
$data[]=$row;
}
}else{
$data=array();
}
?>
