title: How to call only one item from array with $this->config->item CODEIGNITER?
body: <p>I have a default config file in my config directory (default.php). I've loaded it already with autoload file:</p>
  
  <pre><code>$autoload['config'] = array('default');
  </code></pre>
  
  <p>there is my default.php:</p>
  
  <pre><code>&lt;?php
  
  //$config['secretUserHashKey'] = 'g81h6JH18kASPkgAW16jS132sa186h1';
  //$config['secretPhotoNameHashKey'] = 'ghOH3Hs841s98sssp1AHDWPfMHAjd';
  
  // Pages
  
  $config['pagesUrl'] = array(
      'home' =&gt; 'homepage',
      'login' =&gt; 'loginsite'
  );
  </code></pre>
  
  <p>and how I should use it on my view?</p>
  
  <pre><code>&lt;li&gt;&lt;a href="&lt;?=base_url($this-&gt;config-&gt;item('home'));?&gt;"&gt;Home&lt;/a&gt; &lt;span class="divider"&gt;/&lt;/span&gt;&lt;/li&gt;
  </code></pre>
  
  <p>with this example I can get value if mine string is'nt array:</p>
  
  <pre><code>$config['home'] = 'homepage';
  </code></pre>
  
  <p>so what should I do to grab item from my array?</p>
