建立数据库：
mysql -u root -p
show databaese;
create databaes edu;
create databases edu;
use edu;
create table user (uname varchar(10),age int(10));
insert into user (uname,age) values ('rlm',22);

<?php
$mysqli = new mysqli ('localhost','root','111','edu');//连接数据库

$sql = "select * from user ";//查询语句
$result = $mysqli -> query($sql);//返回集
echo "<table>";
while ($row = $result->fetch_assoc()){//循环输出
if ($row['age']<=10){
echo "<tr class='bg_hs'>";
}else{
echo "<tr class='bg_bs'>";
}
echo "<td>学员名:".$row['uname']."</td><td>年龄：".$row['age']."</td>";//输出学员名
echo "</tr>";
}
echo "</table>";
?>

没有执行批量添加mysql语句
批量增加之后：
