#40875 [NEW]: Circular require_once causes fatal error
From: epotocko at gmail dot com
Operating system: Windows XP Pro
PHP version: 5.2.1
PHP Bug Type: Compile Failure
Bug description: Circular require_once causes fatal error
Description:
------------
A circular reference between three files is causing a fatal error.
The simplest example I could reproduce this with is:
B extends A
C extends B
B uses D
D uses C
If class B is modified so that it does not extend class A, the error does
not occur.
Reproduce code:
---------------
ClassA.php:
<?php
class ClassA {}
?>
ClassB.php:
<?php
require_once('ClassA.php');
require_once('ClassD.php');
class ClassB extends ClassA {}
?>
ClassC.php
<?php
require_once('ClassB.php');
class ClassC extends ClassB {}
?>
ClassD.php
<?php
require_once('ClassC.php');
class ClassD {}
?>
test.php
<?php
require_once('ClassB.php');
?>
Expected result:
----------------
If you execute test.php no errors should occur.
Actual result:
--------------
PHP Fatal error: Class 'ClassB' not found in ClassC.php on line 3
