empty doesn't work
<p>I need to check five fields, but only one these fields must be filled and I need to make sure the other fields will be empty. unfortunately it's not working.</p>

<pre><code>if(!empty($_POST['nome']) &amp;&amp; empty($_POST['area']) &amp;&amp; empty($_POST['profissao']) &amp;&amp; empty($_POST['cidade']) &amp;&amp; empty($_POST['estado']))
{
    die("ok");
} 
</code></pre>
