title: MongoDB Library for CodeIgniter (pecl mongodb, not mongo )
body: <p>I just install php mongodb driver by "pecl install mongodb", and the phpinfo page shows mongodb module, that means the module installed successfully, but when I use the code:</p>
  
  <pre><code>"if ( ! class_exists('Mongo') &amp;&amp; ! class_exists('MongoClient'))
  {
  show_error("The MongoDB PECL extension has not been installed or enabled", 500);
  }"
  </code></pre>
  
  <p>in the library file of codeigniter, it shows the error, then I guess maybe this is just for mongo, not for mongodb, so is there any codeingiter library for mongodb? </p>
