title: Session problem in IE and Google Chrome not in Mozilla Firefox
body: <pre><code>if(empty($_SESSION['count'])){
      $_SESSION['count']=99; 
  }else{
     $_SESSION['count']--;
  }
  echo $_SESSION['count'];
  </code></pre>
  
  <p>In Firefox, I get decremented value but in IE and Chrome it does not decrement the value as well as setting the value. Can anyone tell what's the problem?</p>
