有没有办法将json数组发送到服务器端php并将其值插入到表中？

var jsonArray = [
  { "name": "John", "age": 25 },
  { "name": "Jane", "age": 30 },
  { "name": "Bob", "age": 35 }
];

var xhr = new XMLHttpRequest();
xhr.open("POST", "insert.php", true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    console.log(xhr.responseText);
  }
};
xhr.send(JSON.stringify(jsonArray));

$jsonArray = json_decode(file_get_contents('php://input'), true);

// 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, $dbname);
if ($conn->connect_error) {
  die("数据库连接失败: " . $conn->connect_error);
}

// 插入数据
foreach ($jsonArray as $item) {
  $name = $item['name'];
  $age = $item['age'];
  
  $sql = "INSERT INTO your_table_name (name, age) VALUES ('$name', $age)";
  if ($conn->query($sql) !== TRUE) {
    echo "插入数据失败: " . $conn->error;
  }
}

$conn->close();
