如何迭代嵌套的stdClass对象？

function iterateStdClass($obj) {
    if (is_object($obj)) {
        foreach ($obj as $key => $value) {
            if (is_object($value)) {
                iterateStdClass($value); // 递归迭代嵌套的stdClass对象
            } else {
                echo "Key: $key, Value: $value" . PHP_EOL;
            }
        }
    }
}

// 创建嵌套的stdClass对象
$nestedObj = new stdClass();
$nestedObj->name = "Nested Object";
$nestedObj->age = 20;

$obj = new stdClass();
$obj->id = 1;
$obj->info = "Main Object";
$obj->nested = $nestedObj;

// 迭代嵌套的stdClass对象
iterateStdClass($obj);
