Finding out the OS my PHP script is run on

Question

Possible Duplicate:
How to get the OS on which PHP is running?

I need my script to be able to recognize whether it's being run on a Windows or on a Linux system so it can behave accordingly. How do I do that?

EDIT: I need a definite way of doing that, that has no risk of recognizing the wrong OS.

I actually did a couple of searches and didn't come across that. My mistake. — attikiouzel, May 12 '11 at 13:40

Have you looked at the php_uname() function?

I would prefer this solution as it gives a more direct piece of information as per which operating system. – John Cartwright May 12 '11 at 13:55

php_uname and/or the PHP_OS constant will tell you. See the examples here: http://www.php.net/manual/en/function.php-uname.php

Note that anything that comes from the browser to your code can be spoofed, so it's not 'definite'.
