Description:
------------
The include() function is supposed to return the return value of 
whatever code is present in a specified file, or int(1) if no return 
value is produced.

However, when using the interactive shell (php -a), include() will 
always return int(1), assuming that the specified file was found.

Note:
This was discovered while I was investigating the following downstream 
bug in Zend Framework: http://framework.zend.com/issues/browse/ZF-7107.

Also, this seems to be a duplicate of Bug #48056, but I can't find any 
explanation for why that bug was closed as bogus.

Reproduce code:
---------------
# Input to interactive shell
var_dump(include('input.php'));

# main.php (mirrors above input)
<?php
var_dump(include('input.php'));

# input.php
<?php
return "It works!";

Expected result:
----------------
$php -a
Interactive shell

php > var_dump(include('input.php'));
string(9) "It works!"

$php main.php
string(9) "It works!"

Actual result:
--------------
$php -a
Interactive shell

php > var_dump(include('input.php'));
int(1)

$php main.php
string(9) "It works!"

Works for me in 5.3. Does it work for you with current 5.3?

Nope, it's still behaving the same as before:
