首先是建数据库: 字段
id name sex age salary edu bonus city 1 周杰伦_CHOU 1 40 6000 淡江大学 1000 台湾 8 罗大佑 1 50 6000 香港国际大学 50 香港 6 邓紫棋_GEN 0 29 8000 香港大学 2000 香港 7 萧敬腾 1 35 4000 台积电 500 台湾 9 张彬彬 1 30 3000 北京电影学院 20 北京 10 王之涣 1 119 3000 唐朝大学 200 长安城
vscode看全貌全文件:
就这么多文件.
链接数据库为公共文件 public.php
<?php
$host = ‘127.0.0.1‘;
$h_name = ‘root‘;
$h_pwd = ‘root‘;
$char = ‘utf8‘;
$h_db = ‘test‘;
$conn = mysqli_connect($host,$h_name,$h_pwd,$h_db);//链接到数据库
if([email protected]$conn){
echo ‘链接失败‘.mysqli_connect_error();//链接失败返回信息
}
mysqli_set_charset($conn,$char);//设置字符集
首页: index.php
<?php
include ‘public.php‘;
$sql = "select * from stu";
$result = mysqli_query($conn,$sql);
?>
