在footer中添加谷歌分析代码：

/*在底部添加谷歌分析代码*/
<?php
function add_googleanalytics() { ?>
<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){

  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-********-1', 'yoursite.com');
  ga('send', 'pageview');
