title: Memcached is not working on codeigniter
body: <p>I am trying to use the memcached for my large database queries. So far, I have installed the memcached services and it is running fine. Another thing which I am unable to find is <code>php_memcached.dll</code> file for windows 7, 64 bit. There are few but they talk about <code>php_memcache.dll</code>. I have installed that one and I can see in the <code>Wamp-&gt;PHP-&gt;PHP extentions</code> that the extension is running. Finally, I have created the <code>memcached.php</code> file in the <code>application/config/</code> directory and put the following code:</p>
  
  <pre><code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
  
  $config = array(
      'default' =&gt; array(
          'host'      =&gt; 'localhost',
          'port'      =&gt; 11211,
          'weight'    =&gt; 1
      )
  );
  ?&gt;
  </code></pre>
  
  <p>Whenever I se <code>phpinfo();</code> I am unable to locate that memcached is configured. 
  I do not know where I am going wrong. I reckon this is because I have installed <code>memcached</code> service and <code>php_memcache.dll</code> extension. Is this could be the reason ?? </p>
  
  <p>Or what could be potentially reason that it is not working on codeigniter.? </p>
