title: Is it possible to visualize a bunch of functions in UML
body: <p>I'm improving a content management system which uses classes as well as function files (just  php files which contain various functions).</p>
  <p>E.g. I have a class called <code>Admin</code> and a function file which has functions for displaying an overview of the admins, create a new admin, edit an existing admin, delete an admin ...</p>
  <p>The function files use the classes and do the visualization part of the mvc concept whereas the classes are responsible for the controller part.
  The model part is done by a mysql database.</p>
  <p>I know that there a class diagrams in UML.
  Is there a way to extend this diagrams with the loose functions from the function files so that the documentation is complete?</p>
  <p>I'm using Visual Paradigm Community.</p>
