使用下面的語句為什么我的數(shù)據(jù)庫看不到插入的字段

<?php
$link?=?mysqli_connect('localhost','root','');
if($link){
????echo?'數(shù)據(jù)庫連接成功！';
}
else?{
????echo?'數(shù)據(jù)庫連接失??！';
}
$link->query("set?names?'utf-8'");
$name?=?'張三';
$age?=?18;
$class?=?'高三一班';
$ins?=?"insert?into?test1(name,age,class)?values('$name','$age','$class')";
mysqli_query($link,?$ins);
$uid?=?mysqli_insert_id($link);
echo?$uid;
