The PHP 5.0.0 changelog entry has been removed in the meantime. However, the behavioral change in
PHP 5.2.1 pointed out by Sjon is not yet documented.

It seems that Changelog notice is incorrect; see http://3v4l.org/MJUQe The only
difference is that since 5.2 the cwd is returned

Sorry, I meant the Changelog part:
-------------------
5.0.0 Prior to this release, a blank or NULL path would cause realpath() to return the directory
name of the script.
-------------------
which sounds to me as if such behavior was removed since 5.0.0. Correct me if I'm wrong...

I don't see the problem here?
From the manual:
path
The path being checked.
Note:
Whilst a path must be supplied, the value can be blank or NULL In these cases, the value is
interpreted as the current directory.

Description:
------------
---
From manual page: http://www.php.net/function.realpath#refsect1-function.realpath-changelog
---
I'm using PHP 5.3.15 (cli) (built: Jul 31 2012 18:42:11).
When I'm tracking a bug in Yii, I realized that it's the issue of php function realpath().
the reproducing is very easy, just run this in console:
php -r "var_dump(realpath(false), realpath(null), realpath(''));"
Test script:
---------------
<?php
var_dump(realpath(false));
var_dump(realpath(null));
var_dump(realpath(''));
Expected result:
----------------
I should see output as below:
bool(false)
bool(false)
bool(false)
Actual result:
--------------
output:(the actual path depends)
string(22) "/Users/yaowenh/phpunit"
string(22) "/Users/yaowenh/phpunit"
string(22) "/Users/yaowenh/phpunit"
