title: Array push to a key giving null value in php
body: <p>So I am taking some input from json that is the userid. </p>
  
  <p>Then I am trying to find its friends and their blogs and its respective comments. </p>
  
  <p>Obviously the comments will be more than one. So whenever I am doing a array push to those comments to a key in array I get null value in my api response.</p>
  
  <p>I tried to use simple $name['comments'] = $res. but as there will be more than one comments so it replaces the new comment with older one.</p>
  
  <p>please help me solving these problem</p>
