使循环从最新的 id 开始

Question

如何

使循环从最新的 id 开始到第一个 id？

    include 'config.php';
    $con->set_charset('utf8');
    $sql = "SELECT * FROM tablename";
    $names = mysqli_query($con,$sql);
    while($row = mysqli_fetch_array ($names)){
    //here will make loop start from first id
     }

Answer 1

像这样更改 sql 变量。这应该有效

$sql = "SELECT * FROM tablename ORDER BY `id` DESC";
