title: how to make codeigniter route support small and big for first letter without running 2 difference loop
body: <ul>
  <li>All my controller file is start w 1st Big letter.</li>
  <li>my code below if i link to Project/Admin/Career it link to my Career.php</li>
  <li>but if f i link to Project/Admin/career it link to my Admin.php</li>
  </ul>
  
  <p>my question is how do it make $route support both small and big for 1st letter </p>
  
  <p>or i need to duplicated my method_arr to another method_arr1 and run foreach again (with array start small letter ) ?</p>
  
  <p>Ex: Career, career</p>
  
  <blockquote>
  <pre><code>$method_arr=array(
                'Career',
                'Contact',
                'Googlemap',
                'Introduction',
                'Slideshow'
                );
  </code></pre>
  </blockquote>
  
  <pre><code>    $route['default_controller'] = "home";
  
      foreach($method_arr as $method_arr){
          $route['Admin/'.$method_arr] = 'backend/'.$method_arr;
      }
  </code></pre>
