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"

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.

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...

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

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.
