Description:
------------
---
From manual page: http://www.php.net/function.chdir#Return Values
---
The manual does not mention that chdir() emits an E_WARNING in case the directory cannot be changed.

Test script:
---------------
> php -a
Interactive shell

php > var_dump(chdir('/fghfgh'));
PHP Warning:  chdir(): No such file or directory (errno 2) in php shell code on line 1
PHP Stack trace:
PHP   1. {main}() php shell code:0
PHP   2. chdir() php shell code:1

Warning: chdir(): No such file or directory (errno 2) in php shell code on line 1

Call Stack:
    8.4448      62776   1. {main}() php shell code:0
    8.4448      62888   2. chdir() php shell code:1

bool(false)


Expected result:
----------------
Returns TRUE on success or FALSE and a PHP error of level E_WARNING on failure. You can suppress the error output of chdir() by prepending '@' to the front of the function name.

This is a rough adjusted rip from "opendir()" return value description.

Actual result:
--------------
-/-
