PHP - $_POST and $_SESSION
<p>What's the differences between <code>$_POST</code> and <code>$_SESSION</code>? When should I use each of them? I've been searching on internet, but I still don't understand. Please give simple explanation and give an example. Thanks</p>

 can help you to explain the difference</p>
