Instantiating class from string wont really work in php
<p>Ive just started learning namespaces. If I do this:</p>

<pre><code>$a = new Devices\Desktop();
</code></pre>

<p>this works. But I have dynamic class names, so I have to do it from a variable.</p>

<pre><code>$a = 'Devices\Desktop';
$a = new $a();
</code></pre>

<p>this is not working, although its the same. The class is not found. Why?</p>
