This can't be a good idea... I presume you need to use certain OS-dependent
feature. Why don't you just check for that specific feature?

Anyway, in the "Predefined constants" chapter I see PHP stores the value
for you so you don't depend on environmental variables:

Core Predefined Constants

These constants are defined by the PHP core. This includes PHP, the Zend
engine, and SAPI modules.

PHP_OS (string)

Check the variables_order directive in "php.ini". There's also a comment
about it in the file:

; - variables_order = "GPCS" [Performance]
; The environment variables are not hashed into the $_ENV. To access
; environment variables, you can use getenv() instead.
