using return in include files

[Aaron Axelsen <lists@xxxxxxxxxxxx>]

I'm trying to figure out what the desired behavior is of using the
return function to bail out of an include page.

I did some testing, and this is what I concluded.

First, I created the following file:

<?php
if (defined('TEST_LOADED')) {
        return;
}
define('TEST_LOADED',true);
echo "blah blah blah blah<br/>";
?>

I then called it as follows:
include('test.php');
include('test.php');
include('test.php');

The output is:
blah blah blah blah

Second, I changed the test.php file to be the following:

<?php
if (defined('TEST_LOADED')) {
        return;
}
define('TEST_LOADED',true);
echo "blah blah blah blah<br/>";

function myFunc($test) {

}
?>

When I load the page now, it throws the following error: PHP Fatal
error: Cannot redeclare myfunc()

It appears that if there are functions in the include page that you
can't use return to bail out.  What is the desired functionality in this
case?  Is this a bug in how php handles it? or was return never designed
to be used this way?

Any thoughts are appreciated.
