For random numbers you MUST call srand() before rand().

Unfortunately it behaves the same with Windows snapshots.
For case it's not obvious from my fist comment - if I call srand()
before rand() it works well.

Please try using this CVS snapshot:
http://snaps.php.net/php4-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-STABLE-latest.zip
Works fine for me within Windows XP, within Apache and CLI.

Description:
------------
Function rand() without setting random seed by srand() returns always
the same value. It doesn't work only on Windows PHP-CLI. As Windows
Apache module and also on Linux PHP-CLI it works as it should.
Reproduce code:
---------------
echo rand();
Expected result:
----------------
(random value)
Actual result:
--------------
24849
