title: How to check if Controller already exists when already configured route using Codeigniter?
body: <p>On my website, I am loading the content dynamically from database like this</p>
  
  <pre><code>e.g mysite.com/about-us   
  </code></pre>
  
  <p>for this, there is an enrtry in database, so it will load the content for 'about-us' &amp; print it using "page" controller only. </p>
  
  <p>for this what I have done is, I have added below configuration in routes.php</p>
  
  <pre><code>$route[':any'] = "page";
  </code></pre>
  
  <p>but lets say if I already have controller named "about-us" and I want to load that &amp; not the one from database, how can I do that?</p>
