[PHP-WIN] calling a php script

[Gerardo Rojas]

I'm trying to call a php script from another php script.  I have the script name in a 
variable.  Any suggestions on how to implement this?  I tried the "back-tick" and the 
exec.  I even tried doing it with a *.bat file.  Nothing seems to work.  I'm on W2k 
and php 4.3.3
