使用AJAX/JSON将对象数组传递给PHP

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

var jsonData = JSON.stringify(data);

var xhr = new XMLHttpRequest();
var url = "your_php_file.php";

xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");

xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    // 请求成功后的处理逻辑
    console.log(xhr.responseText);
  }
};

xhr.send(jsonData);

$data = json_decode(file_get_contents("php://input"), true);

// 对接收到的数据进行处理
foreach ($data as $item) {
  $name = $item['name'];
  $age = $item['age'];
  
  // 进行相应的操作，如存储到数据库等
}
