Question

提示$data=mysqli_fetch_row($result);有错，请问怎么改呢？

<?php
//1,连接
$conn=mysqli_connect("localhost","root","root");
if(mysqli_connect_errno($conn))
die("无法链接到服务器");
//2,选择数据库
mysqli_select_db($conn,"xuexi51")or die("error");
//3，SQL查询
$sql="SELECT*,FROM liuyanban";

$result=mysqli_query($conn,$sql);

$data=mysqli_fetch_row($result);

print($data);
mysqli_close($conn);
?>

<?php
//1,连接
$conn=mysqli_connect("localhost","root","root");
if(mysqli_connect_errno($conn))
die("无法链接到服务器");
//2,选择数据库
mysqli_select_db($conn,"xuexi51")or die("error");
//3，SQL查询
$sql="SELECT * FROM liuyanban";//多了个，

$result=mysqli_query($conn,$sql);

$data=mysqli_fetch_row($result);

print_r($data); //print不能打印数组
mysqli_close($conn);
?>
