在PHP中从XSS清理传入的JSON数据的好方法

I have a php function that does this to escape HTML tags using wordpress's esc_attr function but I am having to covert the JSON data to an array and then back to an object, anyway to map a function directly to an object?

function get_ajax_data() {
    $data = (object) array_map('esc_attr', json_decode(stripslashes($_POST['data']), true ));
    return $data;
}
