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

The information about the server operating system can be obtained with php_uname() function:

echo 'I have been run on '.php_uname('s');

It also allows to retrieve the full information on the version.
