Seriously Is It this much code to support case insensitive post/get keys? There has got to be a better way...

gistfile1.aw

<?php  
  $caseInsensitivePosts = array('your_desired_cleaned_lower_case_post_var');

   foreach($_GET as $k=>$v)
   {
      $lower = strtolower($k);
      foreach ($caseInsensitivePosts as $requestVal)
      {
         if ($requestVal == $lower && $k !== $requestVal)
         {
            //clean keys to lowercase for calling pages to handle consistent values
            $_GET[$lower] = $_GET[$k];
            $_REQUEST[$lower] = $_GET[$k];
            if (array_key_exists($k,$_GET))
            {
               unset($_GET[$k]);
            }
            if (array_key_exists($k,$_REQUEST))
            {
               unset($_REQUEST[$k]);
            }
         }
      }
   }

   foreach($_POST as $k=>$v)
   {
      $lower = strtolower($k);
      foreach ($caseInsensitivePosts as $requestVal)
      {
         if ($requestVal == $lower && $k !== $requestVal)
         {
            //clean keys to lowercase for calling pages to handle consistent values
            $_POST[$lower] = $_POST[$k];
            $_REQUEST[$lower] = $_POST[$k];
            if (array_key_exists($k,$_POST))
            {
               unset($_POST[$k]);
            }
            if (array_key_exists($k,$_REQUEST))
            {
               unset($_REQUEST[$k]);
            }
         }
      }
   }
?>
