Looking for a good way to detect server platform

Hi,

I'm currently writing a wee library tool in PHP. It generates a few
(actually a lot) of temporary files and directories, so I need to setup
some garbage collection. I can do this a lot more effeciently from the
shell on a POSIX system than writing lots of PHP code, but the former wont
to work if someone tries to run it on a different platform.

(If on Unix/Linux/... I can use 'at now' to sperate the process group, and
use 'find' to delete the aged files).

Anybody got any hot tips on how to detect the platform? (I guess I could
search the $PATH for 'at' and 'find' but I was looking for a quicker fix)

TIA

C.

The predefined constant PHP_OS holds the value 'WINNT', 'LINUX', etc as
appropriate...

this is how I do it

$cwd = getcwd(); //get working directory
if (strstr($cwd, ":")) it is Windows....

Hi Andy,

Ok, I did not know you can insert ":" into a unix path. I would
never have that situation with my paths, since they are totally under
my control -for webserving. In any case, the use of PHP_OS is a lot
better.
