附加GA事件跟蹤，以JSON元素

我想添加事件追蹤到正在轉換爲HTML跨域產品...附加GA事件跟蹤，以JSON元素

該文件位於服務器端和PHP編寫的。 JSON的片斷，我需要追加GA事件如下：

"products": [ 
    { 
     "title": "product", 
     "description": "description", 
     "thumbnail": "http://myurl.com/picture.jpg", 
     "price": "&pound;1.99", 
     "url": "http://link.com" 
    },]

現在，讀了這篇文章對這個一點給了我一些真知灼見：Using google analytics to track hits on an XML web service

難道是這樣簡單的事嗎？

<?php 
//Initilize GA Tracker 
$tracker = new GoogleAnalytics\Tracker('UA-12345678-9', 'example.com'); 
?> 

"products": [ 
     { 
      "title": "product", 
      "description": "description", 
      "thumbnail": "http://myurl.com/picture.jpg", 
      "price": "&pound;1.99", 
      "url": "http://link.com" 
     },$ga->setEvent("Category", "Action", "Label", "Value");]
