通过AJAX将Javascript对象转换为PHP数组

javascriptvar jsObject = {
    name: "John",
    age: 30,
    city: "New York"
};

var jsonString = JSON.stringify(jsObject);

javascriptvar xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        console.log(this.responseText);
    }
};
xhttp.open("POST", "your_php_script.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("data=" + encodeURIComponent(jsonString));

php<?php
if (isset($_POST['data'])) {
    $jsonString = urldecode($_POST['data']);
    $jsObject = json_decode($jsonString, true); // 将第二个参数设置为 true，以将对象转换为关联数组
    print_r($jsObject); // 打印数组以供检查
}
?>
