title: Are PHP MVC Controllers implemented by url rewrite?
body: <blockquote>
    <p>The controller in a Java EE
    application may be represented by a
    servlet, which may be currently
    implemented using JavaServer Faces
    (JSF).</p>
  </blockquote>
  
  <p>But in PHP there is no such servlet,so I guess is it implemented by url rewrite?</p>
  
  <p>So that every request is directed to that controller?</p>
