title: Codeigniter configuration file load
body: <p>I want to use a new file containing constants in Codeigniter so I created the file <code>/config/labels.php</code> </p>
  
  <p>When I try to load it in my controller using <code>$this-&gt;config-&gt;load('labels');</code> and it throws 
  <code>application/config/labels.php file does not appear to contain a valid configuration array.</code></p>
  
  <p>However when I put the code in the constants.php file everything works well. </p>
  
  <pre><code>labels.php 
  
  &lt;?php
  define('CLI_CIVILITE','Civilité');
  define('CLI_NOM','Nom');
  define('CLI_PRENOM','Prenom');
  </code></pre>
