Operating system: FreeBSD and WIN
PHP version: 5.2.6
PHP Bug Type: Strings related
Bug description: logic related; "abc"==0 returns true
Description:
------------
I think there is a bug in the logic when comparing a string to int(0).
I experience this bug on both MS windows and FreeBSD, on PHP 5.2.5 and PHP
5.2.6 and using Apache 2.0 / 1.3.
Reproduce code:
---------------
//Here is three ways of reproducing the same error.
var_dump("test"==0);
var_dump(("anotherTest"==0));
//... and finaly ...
$bool=("abc"==0);
var_dump($bool);
Expected result:
----------------
I expect them all to return bool(false), I expect only "0"==0 to return
true.
Actual result:
--------------
They all return bool(true), nomather what string i compare to 0
