php mysql批量添加数据

<?php

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

// 检查连接
if ($conn->connect_error) {

// 准备批量插入的数据

    ['name' => 'Bob', 'age' => 30],
    ['name' => 'Charlie', 'age' => 35]

// 构建批量插入的SQL语句

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

// 执行SQL语句
