How to use 'use' in php , Getting fatal error
<p>I have learned that I need to use name space in php like I have used in my following code but I'm getting <code>Fatal error: Trait 'SuperClosure\Serializer' not found</code>
I have used it like this:</p>

<pre><code>use SuperClosure\Serializer;
public function set( $key, $value )
   {
    $key = strtolower( $key );      
    $serializer = new Serializer();
    $serialized = $serializer-&gt;serialize($value);



    $_SESSION["HA::STORE"][$key] = $serialized;
   }
</code></pre>

<p>where I am wrong ? please tell me the correct way to use it?</p>
