title: return multiple json results
body: <p>I have to output <code>$var1</code>. To do that, I return results by using </p>
  
  <pre><code>sendJson($var1);
  </code></pre>
  
  <p>And this is working fine for me. Now I want to pass two variables <code>$var1</code> and <code>$var2</code> using  <code>sendJson();</code>. Is it possible?</p>
