title: printing values from object
body: <p>How do I echo the value from the object? In the following example I expect 1105 service number to be printed after "case".</p>
  
  <pre><code>    $vbk-&gt;set('service_no','1105');
      echo "case".$vbk-&gt;service_no;
  </code></pre>
  
  <p>I need to use object for this purpose.</p>
