Operating system: Windows
PHP version:      5.0.3
PHP Bug Type:     Feature/Change Request
Bug description:  Clear screen or ScreenSize

Description:
------------
From a command line php.exe invoked from a cmd prompt under Win XP Pro,
I'd like to be able to blank the screen and/or determine the screen
height.

Motivation:
I have a program that takes several hours to run and it shows several
lines of progress statistics, which are periodically updated.  I'd like to
keep this presentation professional.

I could simulate what I'm asking by interspersing 1000 "\n" whenever I'm
printing an updated set of stats.  However, this puts the info at the
bottom of the screen.  If I could programatically determine the height
(since it might be changed/stretched/shrunk by the user) of the DOS (CMD)
screen in lines then I could compensate for it (and if you give me that,
I'd like to know the width, too, please).  

Alternately, if there was a simple way to blank the screen with the cursor
starting off at the top left, that might be another way to go (sort of a
PHP issued CLS).

Thanks for considering whether this is possible/reasonable,
Csaba Gabor from Vienna

Note:  This is distinct from http://bugs.php.net/bug.php?id=24109 because
(1) as I understand it, ncurses does not apply here because it does not
work for DOS/cmd prompts. (2) I want to reuse the current window.

Apropos:  Perhaps an alternate approach (Ie. feature request) is to ask
PHP to return a handle to its parent process.  Perhaps it is possible to
query that (using Windows APIs) for its properties.
