php 批量写入mysql

<?php

$password = "password";
$dbname = "myDB";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

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

// 准备批量插入的数据
$data = [
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 30],
    ['name' => 'Charlie', 'age' => 35]

// 构建批量插入的SQL语句
$sql = "INSERT INTO users (name, age) VALUES ";
$values = [];

foreach ($data as $row) {
    $values[] = "('" . $conn->real_escape_string($row['name']) . "', " . intval($row['age']) . ")";

// 执行SQL语句
