使用php将xml数据转换为mysql插入/更新查询

<?php
// 解析XML数据
$xmlData = '<data>
    <item>
        <name>John</name>
        <age>25</age>
    </item>
    <item>
        <name>Jane</name>
        <age>30</age>
    </item>
</data>';

$xml = simplexml_load_string($xmlData);

// 连接到MySQL数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = mysqli_connect($servername, $username, $password, $dbname);

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

// 创建插入查询语句并执行
foreach ($xml->item as $item) {
    $name = mysqli_real_escape_string($conn, $item->name);
    $age = mysqli_real_escape_string($conn, $item->age);

    $sql = "INSERT INTO users (name, age) VALUES ('$name', '$age')";
    mysqli_query($conn, $sql);
}

// 关闭数据库连接
mysqli_close($conn);
?>
