On the server with the definition:
file: givememyclassdefinitioninplainphp.php
<?php
readfile('myClass.php');
?>

Then again, I would never never never get class definitions this way. Too
much overhead, huge security risks, slow, waiting for a
connection-error/incomplete file to happen etc.

I would keep a local copy, keep a CVS or SVN repository of the class
definitions, and update now and then according to need.
