The index.php file for my concrete5 app contains
<?php require('concrete/dispatcher.php');
I understand the "require"; I am not sure how the "control" of the application gets transferred to dispatcher.php.

The PHP manual has an explanation for [man]include[/man] that applies to require.
Hint: control is not transferred to the required file -- the required file is read in and "used" as though it were part of the code in the requiring file.
