Strange problem with $_GET
<p>I have a strange error with a $_GET Value. Im using thsi code for a query:
<code>array($_GET['cats'])</code></p>

<p>If I insert the get parameter manually, like: <code>array(3,328)</code> everything works fine. But if I use:
<code>array($_GET['cats'])</code> and submit the cats by URl like <code>?cats=3,328</code> it does not work, What could be the issue? </p>
