title: passing variables in a mvc pattern
body: <p>I have built a system that conforms to the mvc pattern in PHP. The controllers and actions are part of the urls in my application. So I have:</p>
  
  <p>www.example.com/controller/action/</p>
  
  <p>So now I am looking for a way to pass on variables. For forms I just use the post method, but sometimes I would just like to link to a different page and then pass on some variables. </p>
  
  <p>I would like some suggestions on how to do this. I know the Zend Framework has the variables as key/value pairs after the action in the controller using the "/" character as a separator, like this:</p>
  
  <p>www.example.com/controller/action/var1/value1/var2/value2 </p>
  
  <p>Is this the best way?  This is actually the only way I know it's done.
  I am looking for an easy but yet good way to implement it.</p>
  
  <p>Any suggestions are welcome.</p>
