统计按钮点击量的PHP脚本

<?php
// 数据库连接配置
$servername = "localhost";
$username = "username";

$dbname = "database";

// 获取前端传递的按钮标识符
$buttonName = $_POST['buttonName'];

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {

// 查询数据库中是否已存在该按钮的记录
$sql = "SELECT * FROM button_stats WHERE button_name = '$buttonName'";

// 如果存在记录，则更新点击次数；否则插入新记录
if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
