PHP+VUE实现前端和后端数据互通（宝塔⾯板）
基于element和vue的⼀个简单的后台管理页⾯基础模型（这⾥我⽤了php从数据库获取数据然后在JS区域接收了获取的数据。PS：不会⽤axios）
直接附上所有代码：数据库：mywu ⽤户名：root 密码：root 数据表：test
<?php
header("Content-type:text/html;charset=utf-8");
$host = "localhost";
$username = 'root';
$password = 'root';
$db = 'mywu';
//1.连接数据库
$conn = mysqli_connect($host,$username,$password,$db);
if (!$conn) {
die('Could not connect: ' . mysqli_error($con));
}
//2.定义⼀个空数组⽤来接收数据
$usersArr = [];
mysqli_set_charset($conn,'utf8');
//3.获得数据表test的数据
$user_menu = "select * from test";
//4.发送sql语句
$res = mysqli_query($conn,$user_menu);  //结果集的资源
//5.将结果集资源转换成数据
/
/ $row = $res->fetch_assoc();
//while判定条件是否为true是则循环
while($row = $res->fetch_assoc())
{
$userArr[] = $row;
}
