Question

为什么我的php 写不入数据库里面 一直失败 下面是代码？

$con=new mysqli("localhost","root","","classdb");

$con->set_charset('utf8');
if($con->connect_error){
die('连接数据库失败');}

$sql = "insert into student (xuehao,password) vlaues('$email','$password')";
if(mysqli_query($con,$sql)){
echo "成功插入";
}else{echo "插入失败";
}

<?php
$con=new mysqli("localhost","root","","classdb");

$con->set_charset('utf8');
if($con->connect_error){
die('连接数据库失败');}

$sql = "insert into student (xuehao,password) vlaues('".$email."','".$password."')";
if(mysqli_query($con,$sql)){
echo "成功插入";
}else{echo "插入失败";
}
?>

这样试试

推荐使用PDO连接。mysqli是扩展连接
