If all you want to do is to find out what the user's OS is, try this:
$_SERVER('HTTP_USER_AGENT')
Do print_r($_SERVER) to see all it contains.

He wanted to tell the OS of the *server*, hence using a local

Re: [PHP] getting $_ENV variables
Thanks Daniel, Greg, Richard,
I made a script with:
?php
print_r($_ENV);
?
and it results only into: Array ( ) nothing else ...
So it must be caused by a different environment ?
All I want is to check the $_ENV['OS'] within PHP scripts.

Subject: Re: [PHP] getting $_ENV variables
When I print_r($_ENV); from the CLI on 5.0.4 I get a bunch of results, no
problem but no $_ENV['OS'] variable. Further, when I check my phpinfo();
output, there are even fewer $_ENV variables printed than the CLI offers.
I'm not certain about this, Cor, but my guess is that PHP 5.x.x may have
altered the default $_ENV output to hide some of this information --- which is
a good thing, in my opinion, because then you won't just have some
run-of-the-mill script kiddie checking out the details of a box for known
security holes.
Of course, that doesn't necessarily stop ? passthru('uname -a').\n; ?
or checking the $_SERVER['SERVER_SIGNATURE'] variable for the OS
information so perhaps this response is just one of those white-bread
responses. Something to chew on, but you really don't get anything from it.

Re: [PHP] getting $_ENV variables
Cor,
If it's suggesting that it's an array, that's a little baffling, because
that means there are multiple entries (at least two), but they appear to
either be null or otherwise unable to display.
Did you get that result when running the script from the CLI or via the
web?

That last one is actually one of my favorites for simple desktop page

The array ($_ENV) exists, it is just the population of it that has been disabled, thus it's empty. Just in the same way that doing a print_r($_GET) will always display an empty array even if the query string is totally blank, or print_r($_POST) does the same, even though you didn't post a thing to the script. The super-globals I guess must just be created at run-time, and populated later on in the process, by which time the php.ini settings have been taken into account and stopped the action.

How to get $_ENV variables ? I am using PHP version 5.2.0. If phpinfo() shows them, then that is what is there... There's nothing magical about phpinfo() function. It doesn't do much more than your print_r($_ENV) So unless you are running your script in a *DIFFERENT* environment (e.g., CLI or CGI versus Apache Module) you ought to see the same things if you spell $_ENV correctly... You can't even mess up variable scope, since it's a superglobal... No, wait... I think if you write it as a function and then declare $_ENV as 'global' you might actually manage to mess up and end up with your own $_ENV instead of the real one...
