<?php
// 连接数据库
$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询
$sql = "SELECT * FROM 表名";
$result = $conn->query($sql);

// 检查查询结果
if ($result->num_rows > 0) {
    // 将查询结果赋值给变量
    $data = $result->fetch_assoc();

    // 输出变量值
    echo "ID: " . $data["id"]. " - Name: " . $data["name"]. " - Email: " . $data["email"];
} else {
    echo "没有找到匹配的记录";
}

// 关闭数据库连接
