Summary: (integer) 0 == '_'
Status: Bogus
Type: Bug
Package: Scripting Engine problem
Operating System: Windows XP SP3
PHP Version: Irrelevant

New Comment:
Types matter. What is the integer value of '_' ? When you are
comparing
different types, one will be cast to the other. When you cast '_' to an
integer
you get 0. You either need to force both parameters to be of the same
type
yourself, or you need to use ===

That's what I'm doing now, but why is this being flagged as bogus?
Zero is not equal to an underscore, typed or not.

use ===. and try echo (int) '_';

Description:
------------
When testing the expression of integer "0" (zero) equals "_"
(underscore), the
result of the expression is true, when it should be false.
I could not select the proper PHP version number because it was not
listed:
C:>php -v
PHP 5.3.2 (cli) (built: Mar 3 2010 20:36:54)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans
Test script:
---------------
<?php
$index = 0;
if ( $index == '_' )
echo "Bug found.\n";
else
echo "No bug found.\n";
Expected result:
----------------
No bug found.
Actual result:
--------------
Bug found.
