title: Codeigniter: Checking to see if config variable is set?
body: <p>Wondering if there is a way to check if a config variable is set in Codeigniter?</p>
  
  <pre><code>if ( isset($this-&gt;config-&gt;item('configItem'))) {
  //do stuff
  }
  </code></pre>
  
  <p>Seems like something like this should work? The error I get is "Expected: variable".</p>
  
  <p>Thoughts?</p>
