Bug description: Cyclic inclusion of classes
Description:
------------
There is a bug with cyclic inclusion of files with class definition.
There are three classes - A, B, C - each placed in a separate file -
A.php, B.php, C.php - all in the same directory.
B is a derived class of A, C is a derived of B.
So, B.php includes A.php (using require_once), C.php includes B.php.
A.php contains both class A and function f(), which is subsequently
called. f() includes 'C.php'.
When trying to request B.php (or include it from another file) I get Fatal
error: Class 'B' not found C.php on line 4.
Reproduce code:
---------------
Three files here:
--------[ A.php ]--------
<?
class A {}
function f()
{
include 'C.php';
}
f();
?>
--------[ B.php ]--------
<?
require_once 'A.php';
class B extends A {}
?>
--------[ C.php ]--------
<?
require_once 'B.php';
class C extends B {}
?>
Expected result:
----------------
No error when requesting or including B.php.
Actual result:
--------------
Fatal error: Class 'B' not found in /srv/www/test/C.php on line 4
