Shouldn't this line:
class my_child_class extends MY_BASE_CLASSFILE {

Read like this:
class my_child_class extends MY_BASE_CLASS {
 
After all "base_class.php" isn't the name of your class, "base_class" is.

I want to be able to set a base class in a settings file, and then have other
classes extend the base class, but PHP won't let me do what I have tried.

I get the following error:
Fatal error: Class cepweb: Cannot inherit from undefined class my_base_class
in /home/me/my_child_class.php on line 10

ex:

// settings to be set on install of the app
define("MY_BASE_CLASS","base_class");
define("MY_BASE_CLASSFILE","base_class.php");

// require the class file
require_once(MY_BASE_CLASSFILE);

class my_child_class extends MY_BASE_CLASSFILE {
// yada yada
}
?>

Any thoughts on ways to overcome this?

I have tried using a variable instead of a constant, but it didn't work.
