-Status: Open
+Status: Bogus
Type: Bug
Package: Class/Object related
Operating System: Ubuntu 9.10/RHEL 4
PHP Version: 5.2.13
New Comment:
Not reproducible.
Please enable error reporting and make sure display_errors is set to
On.
PHP 5.3.99-dev
PHP 5.3.3-dev
PHP 5.2.14-dev
All these versions report a fatal error:
Fatal error: Class example contains 1 abstract method and must therefore
be declared abstract or implement the remaining methods (abcEx::foo) in
/tmp/1.php on line 4

Description:
------------
if you have an abstract class that gets overridden, if a method that is
overridden has a default where the abstract doesn't, PHP just halts
without any error, warning, or fatal. For small projects this is
manageable, but when you have a large project, hunting down these things
take a long time, such as a multi-thousand lined library loaded with
abstract classes.
These are the folowing versions of PHP that I've tested:
$ php --version
PHP 5.2.10-2ubuntu6.4 with Suhosin-Patch 0.9.7 (cli) (built: Jan 6 2010
22:56:44)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
and
<This is a RHEL box. (Red Hat Enterprise Linux ES release 4 (Nahant
Update 8))>
$ php --version
PHP 5.2.13 (cli) (built: Apr 6 2010 18:40:35)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
Test script:
---------------
runme.php
<?php
include("file1.php"); // Fails here because a method isn't overridden.
// Just halts, no errors with error_reporting on and error output set to
E_ALL.
// The included file never actually executes any code unless the $bar
in
// the abstract class is changed to $bar=null, which fixes the problem,
but
// finding the problem to begin with is the problem.
?>
file1.php
<?php
include_once("file2.php");
class example extends absEx {
function foo($bar=null) {
// Do something
}
}
?>
file2.php
<?php
abstract class absEx {
abstract function foo($bar);
}
?>
Expected result:
----------------
Error: Abstract method not overridden (Line: ##### OR method name)
Actual result:
--------------
# PHP halts suddenly with no error output.
