How to detect if $_POST is set?
<p>I want to know how to detect if $_POST is set or not.</p>

<p>Right now I detect it like this:</p>

<pre><code>if(isset($_POST['value']))
</code></pre>

<p>But I'm not looking if value is set anymore. Basically, any POST will work.</p>

<pre><code>if(isset($_POST))
</code></pre>

<p>I'm not sure how PHP handle this. Perhabs isset($_POST) is always returns true since it's a PHP global?</p>

<p>Basically, how can I do this?</p>
