How to Use Google API to Get Google Analytics Data with PHP

To fetch the google analytics data through google api, you need to enable the google analytics api from google developer console panel.

Use this link to access google api console. Find the analytics api and enable it.

To enable this api, first you have to create a project in it. Just click on Create Project button. After that fill the project name in form and submit it. Now your analytics api get enabled.

You can access this api via Oauth procedure. We are showing an simple way to do this.

For this you required “analytics.class.php” file. In this file all analytics method are defined. We just call that method to show data. For that we need your gmail account access and Google Analytics Profile Id (View ID).

How to get Profile/View Id:

Signin your analytics account. Go to Admin section -> View Settings -> View Id

<?php

  class analytics{
    
    private $_sUser;
    private $_sPass;
    private $_sAuth;
