Does PHP have a function to detect the OS it's running on?

Question

I wouldn\'t know under what keyword to look for this in the PHP database, so I\'m asking here.

Reason I want to know is because of how different Operating Systems handle

Answer 1

I'd recommend php_uname. Just read the explanation from the docs:

php_uname — Returns information about the operating system PHP is running on

I did like the suggestion of PHP_OS above, but be careful, per this note from the docs:

consider using the PHP_OS constant, but keep in mind this constant will contain the operating system PHP was built on.
