Answer 1

嗨简单的mysqli内置function用于此

成功后insertion只需拨打此function

即可

if (mysqli_query($conn, $sql)) {
    $last_id = mysqli_insert_id($conn);

}

或如评论中所述，您还可以query运行last inseted id

if (mysqli_query($conn, $sql)) {  

  $result= mysqli_query($con ,"SELECT id FROM Table_name ORDER BY id DESC LIMIT 1 ");
$row = mysqli_fetch_assoc($result);
$last_id = $row['id'];

    }

Answer 2

$ result = mysqli_query（“SELECT * from tablename where id ='”。mysqli_insert_id（$ conn）。“'”）;
