title: different methods in passing parameters in Cakephp
body: <p>I am using cakephp v1.26.<br/>
  I got a function in a controller like this:<br/></p>
  
  <pre><code>class testingsController extends AppController{
  
  function testing($id=null){
  $recieved = $id;}
  
  }
  </code></pre>
  
  <p>I am not sure if there are any better ways to pass a parameter to the Action testing.<br/>
  But I have come across some web sites and got these two methods.<br/>
  Is there any difference in the following parameter passing methods?<br/></p>
  
  <pre><code>1. url/testings/testing/1
  2. url/testings/testing:1
  </code></pre>
