if(isset($_GET['w'])&&$_GET['w']>=0&&$_GET['w']<=65) not working as it should
<pre><code>   if(isset($_GET['w'])&amp;&amp;$_GET['w']&gt;=0&amp;&amp;$_GET['w']&lt;=65)
</code></pre>

<p>when <code>$_GET['w']</code> has a value of (for example) <code>ccc</code> the condition becomes true whereas it should only accepts numbers from and including <code>0</code> to and including <code>65</code> </p>
